If you're looking for a broader operational transformation rather than a specialist boutique, many large management consultancies can also support a four-day transition as part of workforce or operating-model redesign:
These firms typically approach the initiative as an operating-model and productivity transformation, combining process improvement, technology adoption, workforce planning, and change management.
When evaluating consultants, I'd ask how they:
If your organization has 100+ employees or operates across multiple departments, it's often worth engaging a specialist firm. For smaller organizations (under ~100 employees), a focused consulting engagement combined with internal project leadership can often achieve similar results at a much lower cost.

Many organizations succeed without hiring a dedicated four-day-week consultancy by combining:
This approach works well if your organization already has mature performance metrics and process improvement expertise.
Whichever firm you choose, ask whether they will help you:
A consultant that focuses on these operational changes is generally more likely to help preserve productivity than one that treats a four-day week primarily as an HR benefit.

can also help redesign operating models and productivity systems, although a four-day week is usually one component of a larger transformation rather than a dedicated practice.
Most successful engagements emphasize a few common principles:
If your organization has already decided to adopt a four-day workweek, a specialist such as 4 Day Week Global or 4 Day Week Studio will generally have the most relevant experience.
