Introduction

MT Højgaard is one of the leading construction companies in the Nordic countries. The companies sustainability department is working towards a more sustainable future in the building industry and a part of this is looking at the waste management on the construction side. By collecting more waste for reuse on the construction side the buildingside does not only become more sustainable. The right waste management is also beneficial in in terms of certified buildings (DGNB), the economics of a building project and the selling argument for choosing MT Højgaard over another company. From this project we will find solution for how to make sure that the waste is mannaged correctly by the use of project management tools. A part of this is looking and the behavior of the craftsmen and how to change this and looking into the economics of the case. The project is dividend as described in the overview.

Maslow's Hierarchy of Needs

Hierarchy of Needs

The "Hierarchy of Needs" theory was written by a psychologist named Abraham Harold Maslow through studying the lives and motivation of people who were successful like Eleanor Roosevelt and Albert Einstein. Humans, in general, are motivated with needs that are unsatisfied and basic needs to be satisfied before the complex ones. Maslow divided his pyramid into five different types of needs i.e. physiological, safety, love, esteem, self-actualization. The urge to satisfy the needs with time passing by increases, however people after gratifying the basic needs first moves onto the next on their mind.

The project managers with the help of this theory can create a hierarchy of needs to achieve their objectives since they are directly involved with the team. They need to understand the needs and motivation for the project's aims because in case of dissatisfaction the level of efficiency might reduce. Therefore for an efficient and effective team, the project managers need to consider the factors and create a more flexible strategy in regard to needs and cultural background, etc. While some behaviors have more motivations, Maslow noted that any behavior is determined by a multiplicity of basic needs rather than one.

Physiological Needs These are the basic needs that are for survival and universal for human beings. Primarily these needs should be satisfied in order to be motivated towards higher needs i.e. breathing, sleeping, eating, etc. Unless these needs are met others need an unfulfilled. This aspect is essential for a project manager and it needs to be satisfied with the team since physiological conditions are critical. Facilities should be available to the team members such as eating, drinking and resting while enough rest is required before work.

Safety Needs Safety needs are second after physiological needs are gratified. Humans will usually think about their safety, which helps them be consistent and stable. Categories of safety can be freedom from fear, dependency, security, stability, etc. The project manager needs to focus on the safety needs of their team after physiological needs are met. The project manager needs to understand the psychology of each team member and needs to create an environment where the team members feel secure. The project manager also needs to make sure that the team members receive their salaries in time, are healthy and safe. The team members must not be in fear of getting fired due to minor faults otherwise they will not be able to work as efficiently.

Love/Belonging Needs The fact that humans are social animals, therefore, it makes them feel good when they are part of a team/group or around loved ones. The absence of this can cause a person to be depressed, cause social anxiety and loneliness. In terms of management's perspective, belonging to the team is one of the most critical needs. It is the duty of the project manager to create an awareness of being a team within each member and bring them together by arranging social events. This way collaboration becomes smoother and there is efficiency in the team. The members work better when they feel they are a part of a team towards a common goal. The team members should also feel like they are treated equally and with justice as well as respect or else they might lose the feeling of being an equal team member.

Esteem Needs Esteem can be of two types, self-esteem which is a product of becoming a master in a particular task while the second one is being respected and given attention from the team members. After a person's need for belonging is satisfied they want to see recognition and respect in life. For example, when a scientist makes a breakthrough and receives an award, they will see respect from the community which satisfies their level of self-esteem, while it is also imperative that a person builds their self-esteem internally. From a project management perspective, a project manager should essentially show respect to the team members and appreciate their contribution to their team to boost their esteem. This makes the team members more confident and creative while project managers should also satisfy their own esteem needs.

Self Actualization This is the top of the hierarchal pyramid of needs, in which Maslow argues a person ought to be what he is. In other words, a person who loves music must make music, while an artist must produce art which is essentially called self-actualization. Finally, Maslow argues, curiosity and need for knowledge is the top of the pyramid. In the scope of project management, for a project manager, it is important to identify the motivation of a team member to be in the team, since it is different with each individual. In the process of team building, the project manager should learn the team member's purpose and their expectation. When the team member has a specific interest in the project and curious for gaining knowledge, the success chance of the project increases.

• Benefits

Maslow's Hierarchy of Needs is an important perspective for project managers to understand their team members' needs and motivations. They can use such information to create the most efficient work environment which will aid the quality of the project also the progress.

• Limitations

There are certain limitations for Maslow's perspective which are stated as follows:

• For different people the motivation is different such as to some love is more important than self-esteem.

• People who are privileged and have never experienced any lack of basic needs can undermine its importance.

• Some people can undermine other values for sake of their own beliefs such as religion, national identity, etc.

Star Model

Star Model

The Star model is an organization design framework that management use to influence the behavior of the employee. The Star model design policies have five different categories used as tools to shape the decisions of an organization effectively. They are as follows:

Strategy Traditionally, the first component to be addressed initially in the Star model is the strategy. It is a tool used to determine the direction of the organization. It specifies different aspects of a company, like the objectives needed to achieve and the values of the company. It helps in identifying sources for the company's advantage.

Structure It determines the location of authority/power for decision making. The policies are divided into four areas:

• Specialization, it refers to the numbers and the type of specialty required to complete the tasks.
• Shape, it refers to the number of employees in each department at every level of the company's structure.
• Distribution of power, it refers to the power movement within the departments dealing with different issues.
• Departmentalization, it refers to the formation of different departments at each level of the company's structure, they have usually formed in different dimensions i.e. markets, workflow, function, products and customers, geography, etc.

Processes It shows the information flow and response to IT. This cut across the structure of an organization; after structure, processes is the second most important definition in the star model. The processes are in two ways,

• Vertical, it refers to the budget process and also business plan, allocating resources for talent and funding.
• Horizontal or lateral process, it revolves around the workflow i.e. launching new products or development, and/or customer order fulfillment which can be done through voluntaries or supervised teams.

Rewards It is a system to motivate people for better performance and strive for the goals of an organization. To bring the goals of the employee and the organization on the same page. The policies are defined around raise, bonus profit or salary policies, etc. Other ways can involve awards, recognition within the company for tough assignments. It should be in harmony with processes as well as structure.

People The last tool is towards the people where policies are made to define the skills of the employees. HR policies such as selection, recruitment or job training, etc are governed in this domain. Policies are always successful when they are more consistent with all the other design areas connected. HR policies help build the direction of the organization i.e. flexible company requires flexible workers and matrix organization requires employees who are able to solve conflicts, HR always develops employees and the capability of an organization.

• Benefits

The Star model has different benefits within an organization and in the overall management as well. The structure was the important aspect which most design efforts were put into without putting in much work in the other aspect. However, the Star model helps to recognize processes, rewards, people, etc to be as equally important and worked on. Another benefit of the model is to identify and overcome any negatives within the structure. If the management identifies the negatives within the structure all the other policies can be designed to counter them.

• Limitations

There are certain limitations for the Star model, stated as follows:

• It is limited in the calling out key elements including the inputs and outputs, as well as the performance.
• It also does not provide performance variables of the organization.

Gantt Chart

A Gantt chart is commonly used in project management to show the activities of the project by displaying it against time. A typical Gantt chart consists of the activities listed on the left-hand side of the chart and the time is listed at the top. To put in simple words, a Gantt chart is a visual representation of the task over a certain period of time. It is commonly used to plan projects of all sizes and is useful to show the work that has to be completed on a particular day. The start and end dates of the project can be easily viewed in the Gannt chart hence making it easier to manage the schedule. A typical Gantt Chart consists of the following elements:

• The start date of the project
• Information about the task to be performed
• Who is working on each task?
• Estimated time for the completion of the task
• The end date of the project

The Gantt chart can be planned on paper but it gets hard to draw it if the project is complex. Hence most of the Gantt chart is created on excel or with project management software.

Advantages

• Easier to understand: The tasks can be complex and hard to understand when it is not visually represented, but the Gantt chart makes it easier for people to understand as most of us think in pictures.
• Organizes thoughts: The Gantt chart breaks down a complex problem into smaller processes which can be understood and solved easily.
• Depicts clearly what needs to be done: the Gannt chart if produced in a nice way with high-level tasks properly organized and the resources allocated accordingly, it clearly depicts if the project will be successful within the given timeframe or not.
• Helps set realistic time frames: The bars on the Gantt charts indicate the period of time required for a certain task to be accomplished.
• Its highly visible: it helps people understand the process better and the start and end dates of the projects as well. It also shows which part of the project is currently under progress and also the objectives of the project.

Limitations

• The Chart can get extremely complex: The number of people employed and resources used in the project can be quite large. Usually, software’s are used to take care of the complexity of the Gantt Charts, however when the project gets too complex a number of skilled people are required to manage the Gantt Chart.
• The size of the bar does not indicate the amount of work in the task: the bar on the chart only indicates the time frame of the task. It is not possible to estimate the number of resources that are actually required to complete a particular task.
• Need for constant update: There is always a need to update the chart constantly as the project gets bigger because as it gets bigger there are always changes associated with it. One of the disadvantages of not updating the Gantt is that it will be ignored if small changes are not updated in it.
• Difficult to see on a sheet of paper: Since the software products need to be viewed on the computer screen, which is usually viewed in segments to be able to see the whole project. It is difficult to show the details of the project to the audience.

SWOT

Definition

Fish Bone Diagram

A SWOT diagram is used to establish an overview of a company’s current situation both external and internal and to find out the future direction of the company [1]. A SWOT analysis consists of 4 categories.

1) Strengths: Strengths are internal factors meaning that they represent the resources available within the company. The strengths should be build up within a company and lead to competitor advantages over other companies.

2) Weaknesses: Weaknesses are also internal factors and represents instead the problems within the company. The weaknesses should be set in focus so the company is aware of them and therefore can work around them or improve them. These can be used to set the operational and people goals.

3) Opportunities: Opportunities are external factors since they describe the things that are going on in the relevant societies and markets that the company could potentially benefit from. This in terms of what the company should invest its money in and which future goals they should aim for.

4) Threats: Threads are also external factors since the movement of the society and markets can also thread or limit the companies to such an extend that they are forced to take action. Threads should be monitored until they either disappear or becomes bigger so action should be taken [2].

The categories should be listed in a SWOT diagram like shown in the picture. Based on the intersections between the categories, the final strategy for a company can be planed out. The method should make it clear where the future for the company lies. Should the company try to improve themselves by focusing on their current weaknesses or should they instead rely on the strengths the company does already have?

Benefits

The SWOT analysis is a nice tool to simplify a huge amount of data so it becomes more manageable. For the company the results can be an eye opener to what potential threads and opportunities markets and societies can provide. When a goal is set for the company the method can also be used to identify which other tools could come in hand to reach the final goal.

Limitations

The method is great since it simplifies a huge amount of data. The downside to this is that the model could also end up being simplified too much and key points could be left out. If no simplifications is done on the other hand, the model could end up very big and confusing. The analysis are not really including any limitations in terms of level of detail or level of simplification which could both be a problem. Another limitation of this method is that the result is only reliable with the exact data given in the analysis. If anything changes or if unknown factors appear it could have a great impact on the final result. There are also no requirements for the level of actual data required for the analysis and the result is therefor only as reliable as the inputs. Because of that it should also be taken into consideration who did the analysis since the result could be colored form this.

Expectancy Theory

Definition

Expectancy Theory

Expectancy theory is a motivation theory build on the expectancy of a good result or outcome. It covers the three factors that determine a person’s motivation; expectancy, instrumentality and valence. The level of expectancy in a n outcome determine the level of effort which is expected to be needed to get a certain result. If a person believes that a high level of effort lead to a high performance the motivation will be high.

In order to achieve a good outcome both the expectancy and the motivation must be high. It is the managers responsibility to ensure the workers are motivated and believe that a high effort leads to high performance and result in a good outcome.

Instrumentality describes the perception about the level of effort which will lead to a good outcome. People are motivated to perform high if only the think a high performance will lead to a good outcome or result.

In expectancy theory the valence is important to consider when motivating employees. The desirable outcome is different from person to person, so to ensure a high motivation it is important for a manager to know what has a high valence. This can be pay, accomplishment or enjoying work.

If all these three factors are high the motivation will be high. On the other hand if one of the factors are low, the motivation is most likely to be low. Regarding waste management, the theory can be relevant to use as the waste sorting is a new or improved procedure that need to be implemented. The motivation to do that for the crafstmen is important to get the desired outcome – better waste sorting.

Benefits

The theory is good to use when motivation is a high priority or issue in the desired goal. As motivation does not comes by itself, the theory is relevant as it describes the expectancy behind the motivation an not only the motivation itself.

Limitations

The theory is very simple - motivation needs to come from a high valence. Motivation might be bigger than that or more complex than it is possible to detect with this theory.

Fish Bone Diagramme

Definition

Fish Bone Diagram

A fish bone diagram is used to identify the cause/causes of an effect or in other words, to look at a problem and its origin/origins. The diagram has its name from the visual structure of it but is also referred to as the Ishikawa diagram, which is the name of its creator. The procedure of using the diagram can very easily be divided into four steps as shown in the figure.

1. First the effect that is going to be investigated is defined and placed in a box on the right side of the diagram.

2. A horizontal line is then drawn from the effect box creating the spine of the fish.

3. All causes for the effect is defined and attached to the spine which leads to the effect. Examples of causes could be the three M’s (Materials, Methods, Machines, Mother Nature, Manpower and Measurements ) or the three P’s (People, Process, Policy , Plant, Program and Product) [F2].

4. Depending on the complexity of the effect there might occur sub-categories. After these have been defined, they should be attached to the causes.

The causes of the effect can be found by brainstorming or waste walks[F2].

The diagram helps getting an overview of the causes of a problem and therefore defines which changes should be made in order to resolve a specific problem. This tool might come in hand when we have to identify the causes behind why too big amounts of materials are send to incineration rather than to reuse.

Benefits The method supports idea generation for root causes of a problem. The more brainstorming and reflecting the bigger the opportunity becomes for finding the necessary change that solves the investigated problem. From the diagram the causes gets also visualized which means that it gets easier to get a quick overview of causes. This can be used to give the stakeholder an easy overview of the causes behind the problem. Further more, it also makes it possible to hold root causes up against each and thereby to get an overview of which root causes is repeated.

Limitations One of the disadvantages of this model is, that depending on the complexity of the problem the diagram might get more compressed and hard to navigate in and the clear overview might be ruined. Also it can be hard to connect the root of the main problem across many different causes.

Efficiency and Effectiveness Matrix

Definition

Efficiency and Effectiveness Matrix

The efficiency and effectiveness matrix is a common used project management tool. The main purpose with the tool is to recognize and detect the courses of low efficiency and effectiveness in the current situation so it can be improved. It is a tool that strives to reach the goal for a high performance regarding providing a service or product for the costumers. Efficiency measures how well the resources is used to achieve the goals and effectiveness measures how appropriate the goals are.

The matrix consists of two axes; a vertical which goes from low to high and a horizontal going from low to high. This matrix creates four boxes; low efficiency/low effectiveness, high efficiency/low effectiveness, low efficiency/high effectiveness, high efficiency/high effectiveness.

• Low efficiency/low effectiveness

The wrong goals are being chosen and the resources are used in a poor way which result in a low quality product that is unattractive.

• High efficiency/low effectiveness

The wrong goals are being chosen but the resources are used in a good way which result in a high quality product that is unattractive

• Low efficiency/high effectiveness

The right goals are being chosen but the resources are used poorly which results in an attractive product that is to expensive

• High efficiency/high effectiveness

The right goals are being chosen and the resources are used in a good way which result in an attractive product that is affordable

In the case of waste management, the tool can be useful to detect the courses of why waste sorting on building sites are not working and help to figure out how to improve that.

Benefits

The efficiency and effectiveness matrix is good to show the current situation in a company. It can provide a overview of how the efficiency and effectiveness in a company is and help in the process of improving the two factors.

Limitations

The matrix provides an overview of the situation in the company or organization. It is up to the user of the matrix to decide the way to use it and thereby the detail level. It is important to use a certain level of detail to be able to use it properly and to get a useful outcome. It can be easy just to use it with a low level of detail which will not lead to a useful outcome.

Value Propositions Canvas

The value proposition canvas is a tool that helps us ensure that a product or service suits the needs of the customer segment and also helps us to deliver a product or a service that is valued by the customers. The canvas was invented by Dr Alexander Osterwalder as a framework so as to ensure that the product or service is designed to fit into the market. The tool can be used when an existing product needs refinement or when a new product is being designed from the start. The value proposition canvas usually is made up of two different blocks which are the value proposition offered by the company and the customer profile. The customer profile is important because it is what adds value to the company’s offering.

The customer profile consists of 3 main features, that is,

• Pains- Pains can be the negative emotions, risks, and experiences that a customer has to undergo in the process of getting the job done.
• Gains- The Gains talk about what is actually desired by the customer from the product and also speaks about what would increase the chances of the customer adopting the value proposition of the company.
• Customer jobs- Customer Jobs can be defined as the job that the customer is trying to do, it can also be a problem that has to be solved by them or a wish they need to satisfy. The tasks that a customer needs to fulfil can be social, emotional or functional in nature.

A separate profile has to be created for different customer segments as each segment is unique and has a well-defined set of pains, gains, and jobs.

On the other hand, the value proposition consists of,

• Gain creators- it defines how the service or a product adds value to the customer and creates gains
• Pain relievers – It describes how the product helps customers overcome their pains in doing a job.
• Products and services – It speaks about the service or a product which creates gains and relives pains which in turn creates value to the customers.

After listing out both the blocks of the value proposition canvas a fit is achieved when the product addresses the most significant pains and gains from the customer’s point of view.

Benefits

The Value proposition canvas is a great tool which helps in determining the needs of the customer which in turn lets the company design Business model in a way that it perfectly matches the customers' demands. The method used in the canvas for the collection of customer data is fairly simple. By determining the needs and requirements of the customer, the business models of the company can be effectively designed. This makes sure that no time is wasted in designing products or services in which the customer might not be interested and eventually lead to profitability.

Limitations

• Not looking at the value proposition canvas as two separate building blocks: It is important to be able to distinguish between the two elements of the Canvas. The customer profile is something that gives the user some idea about the customers' preferences and needs. The things that are mentioned in the customer profile are outside the direct control of the company. Whereas, the Value Map contains the jobs, pains and gains of the targeted customer segment and is within the realm of control.
• Mixing several customer segments into one canvas: Mixing several segments of customers into one canvas is a common mistake the companies make. This can cause a lot of trouble as different segments of customers to have different pains, gains and jobs. Mixing up of the segments cause a lot of confusion in which segments information is being observed.
• Creating a customer profile through the lens of your value proposition: It is important to be able to observe the customer segment without any bias. Most of the times it so happens that project managers only start listing the jobs, pains and gains in such a way that the product or service that is developed is able to solve all this. They fail to see what the customer really needs and what are the reasons that are making them behave in a particular way
• Focusing only on functional jobs: Once the customer profile is completed then the customer job is labelled as functional, emotional or social in nature. But most commonly managers tend to label the job as functional but it is really important to think beyond and realize the social and emotional jobs that are actually pushing the customers.
• Trying to address every customer pain and gain: It is a common tendency to link every pain, gain and the job of the customer profile to the value map. But it is unrealistic to believe that the product can satisfy every aspect of the customer profile. Trying to achieve this a waste of time that can be used to do better things and as a result, people end up not performing well in any one of those things which will, in turn, leave the customer unsatisfied.

Problem Tree

Definitions

Problem tree

The problem tree is a central tool of many project planning. The function of this tool is to find solutions on the problem by mapping the causes and effects. This is done by use the similar essential tool as in mind mapping, but where structure is a focus element in this method. The solution will be a prioritised presentation of a problem, its causes and consequences.

The problem tree is a tool based on the general tree diagram, which is a tool used to communicate the hierarchy of elements in a project and to clarify the relations the between main, subordinate, and supporting ideas.

The use of the tool is divided in four parts

• First a brainstorming is used to identify the major problems of a project. Each of these problems may result in a problem tree analysis. One problem is chosen.
• The possible causes to the problem are defined. The causes might be responsible for the problem situation but can further be causes of other causes. The causes can have internal relationships or be directly related to the main problem. All causes are being listed.
• When all causes are found, the consequences can be defined. As the causes, the consequences are being listed with their internal relationships.
• When all elements of a specific problem have been identified, the problem tree can be presented. It is viewed as a tree, where the causes are the “roots”, the main problem is the trunk and the consequences the crown.

Benefits

The advantages of using the problem tree is understanding the problem by breaking it down. By doing it in this way, the chunks will be easier to analyse and understand. Further these will be more manageable when chunking up and down. By expand and elaborate the problems, causes and effects it might be easier for all stakeholders to understand, because of a shared sense of purpose and action. This will clarify the processes in the different stages, and the different stakeholders and participants will be related and connected to specific parts. The issues forward will further be identified and thus handled early in the process, which e.g. can prevent a leak in the budget.

Stakeholder Analysis

The stakeholder analysis is a way to manage the stakeholders in a project, which is often used by project and program managers.

Definition

A stakeholder analysis is a process of identifying people, which is involved, affecting or affected by the project or the problem going to be solved. The focus is to map them in groups of interest and influence and find out, e.g. how to communicate to each of the stakeholders to avoid conflicts. Further this tool is a good way to define and understand the goals and plans for each stakeholder.

The analysis can be based on more tools. In the following four different tools will be mentioned and explained. Current for all tools are, that the stakeholders have to be determined and identified at first. Stakeholders is basically all persons or companies, which have an interest or influence on the project scope; it is all from the general public to investors. The stakeholders can then be grouped by using tools.

• Stakeholder map: All stakeholders which either have an interest or a influence on the project are being identified. The stakeholders are being connected to eachother to visualise their relationships and thereby point out the key players and their specific roles related to other stakeholder.
• Interest/influence matrix: This tool can be used to classify the individual stakeholder's power and interest in the program and thereby appreciate the needs of the stakeholders. All stakeholders are placed in a graph based on their power or influence on the program. When placing the stakeholders their internal relation will be visualised. The tool can be used both before and after a project to see the change of mindset or value for the individual stakeholder.
• Stakeholder and benefit mapping: This tool is a scheme of interests and stakeholders. All stakeholders are placed on one side and all interest are placed on the other side. The parts are being connected crisscross. By using this tool, the most important and common focus areas can be identified.

Benefits

The benefits by using the above-mentioned tools of stakeholder analysis is to effective sort the stakeholders into categories. The tools can help identifying, monitoring and informing the different stakeholders in the correct way and thereby involve them in the right processes and decisions. By using these techniques, the stakeholders, which have an interest in the program, can be analysed and their needs can be covered as good as possible.

Five Whys

Definition

The technique Five whys is developed in the 1930s by a Japanese industrialist and inventor, but the method is still used today to encircle problems. The tool is aimed at people, which is working with the project and have hands-on experiences. This tool is meant for simple problems and not for critical problems, because the method can lead multiple reasons and causes, but only one of these are chosen in the further development, and this can lead to pursue of a single track. This can be a good solution, when making decisions about minor problems, but not with complex issues.

By using the question why, the focus area or objective of the project will be clarified. It is done by moving up in the hierarchy in the work breakdown structure and thereby find the essential of the project. The process of using the five whys is a simple process, where a team defines a problem and write it down. First why will be asked, and the team have to discuss why the problem have occurred. The most thorough issues are written below the problem. Four more whys are asked and the same procedure for the answers are being done. When all five whys have been asked, the root causes can be addressed, and the solutions that can prevent the problem can be discussed.

Benefits

By using this tool both minor and major problems can be analysed by having a discussion about the five whys, and in this case the issues around the project of waste management can be clarified before taking big decisions.
