When interacting with others to achieve an objective through the process of collaboration, a key consideration is who to include. 

As a rule of thumb, the more people involved the longer it takes to achieve a conclusion.  The quality of the result can be impacted, theoretically more input leads to a stronger foundation for action.  

The shifting balance

Fast or slow, high or low quality are considerations but there is not always a direct correlation between involvement (who and how many) and the results.  

The balance between who to involve and when is very much dependent on the context of the situation.  The important aspect is considering the balance before starting the collaboration. 

Additionally as information is uncovered or objectives are modified it may make sense to shift the participation balance. 

Participation Roles

When working collaboratively it is important for the participants to be clear on what is expected of them.  Being inclusive does not mean full mandatory participation by all the stakeholders. 

Feedback can be solicited through a number of methods from face to face meeting to a casual water-cooler conversation.  

Effective collaboration is often founded on planning (as with so many things).  That is who should be part of the process, when and what is their role.  

Thinking this through before beginning work on the objective is will enable the collaborative processes to proceed efficiently. 

Ultimately, planning for inclusion, making changes as things progress, is the better approach and more likely to avoid disgruntled stakeholders whom were not fully communicated with in advance (but thought they should be).
