A charrette is an intensive, multi-disciplinary workshop with the aim of developing a design or vision for a project or planning activity. Charrettes are often conducted to design such things as parks and buildings, or to plan communities or transportation systems. A charrette should take place at the beginning of the project, when the design team can engage with all the stakeholders, including the client, users, consultants, contractors, regulators, and community members. A charrette at this stage can help to:

Establish clear goals and objectives for the project

Identify opportunities and constraints for the site and program

Generate creative and innovative ideas and solutions

Foster collaboration and consensus among diverse perspectives

Reduce conflicts and delays during later phases of the project

Enhance communication and trust among the project team

The other options are not appropriate phases for a charrette. Post commissioning is too late to influence the design or planning of the project. During the design process, some decisions may have already been made or some stakeholders may have been excluded. During the construction process, changes may be costly or impractical to implement. References: : Charrette
