The best proxy of workstream organisation is the structuring of the case interview.
The workstream organization is performed by the manager, who will break down the initial engagment into multiple independant workstreams. This is a key work that will condition the futur success of the team :
- Independant : each workstream is independant. It can ben conducted by one or several consultants and have interactions with the other workstream, but it has it's own deliverables
- Exhaustive : all together the work stream cover the whole scope of the engagement
- proper size : we foster simplicity and try to create workstream with the right size (not too small, not to big) so it can be manager by a workstream leader
Hope this helps
