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
Xxx
Example
Definition
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.

Expectancy Theory
Xxx
Definition
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.

Efficiency and Effectiveness Matrix
Definition
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.[1]
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.
Advantages 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.

Problem Tree
Definition
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. [1]
The use of the tool is divided in four parts [2]
- 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. [3]

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.
- Interest/influence matrix: the stakeholders are placed in a graph based on the power or influence on the project. This graph can be made both before and after a project to see the change of mindset or value for the individual stakeholder.
- Stakeholder and benefit mapping: a scheme of interests and stakeholders, where the two parts are being connected crisscross. By using this tool, the most important focus areas can be identified.
- Stakeholder map: The identified 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. [1]
