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.

Value Propositions Canvas

Definition

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 a 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 start. The value proposition canvas usually is made up of two different blocks which is 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, • Customer jobs • Pains • 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.

Pains can be the negative emotions, risks and experiences that a customer has to undergo in the process of getting the job done. Customer Jobs can be defined as the job that the customer is trying to do, it can also be a problem which has to be solved by them or a wish they need to satisfy. The tasks that a customer needs to fulfill 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 speak 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.

Problem Tree

Definition

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.

• 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.
