Not all engagements must be executed in person by a consultant. In fact, some assessments are more efficient and cost effective when done virtually. Virtual engagement elements can be more time flexible for participants, it supports better time management of the engagement processes, it can help to better support confidentiality and anonymity for employees when engaging with consultants. It also supports the reduction of ancillary expenses (e.g., travel, meals, etc.).

Physical engagements make sense if you are facing a crisis or eminent change requirement. Trying to determine a better way of a work approach, dealing with process and procedural challenges, addressing team dynamic issues, looking to realign.

Clarity of needs will drive the most efficient and effective approach recommendations.
