Until recently, most of the architectural projects had only two players - an Architect and a Client Architect was commissioned by a client and did what that client wanted. Now, end users, citizens, communities, voters and ordinary people want to have a say in projects that are provided for them. The days of an Architect being a tool of moneyed clients and politicians are gone. Social and political changes in the second half of 20th century provided a platform for affirmation of individual and collective rights of citizens to take active roles in decision-making. In the field of Architecture, this in particular applies to the process of design. What was once a one-way street for decision-making is now a profoundly different - multidirectional process of initiative, consultation and agreement between all parties that are or will be directly or indirectly involved in a project. In this way completed projects are the result of a variety of contributions of all stakeholders, thus potentially better meeting a broader variety of their needs and expectations. Stakeholders'participation is required not only during the design, but also after the completion of a built project. Once they start using'their'finished project, they provide feedback about its qualities and shortfalls. This is done through the Post Occupancy Evaluation (P.O.E.). Data collected in this way can then be used to revisit the original design and draw lessons from it, making the next design better suited to the stakeholders of future projects. These laborious, repetitive and complex tasks were difficult to achieve without spending vast amounts of time and resources. This process threatened to be detrimental to the overall success of a project.
