I was curious, the theory seems appealing, but how well does it work in practice in an organization where stakeholders are used to, and comfortable with the traditional budgeting process? I'm used to the traditional process, and know how much of resistance that ZBB would have had in the organizations that I helped in my career.
War stories welcome. What worked, what didn't? What were your lessons learned? Did it move the needle? Would companies benefit especially in a capital rationed post COVID world? Have you used a hybrid approach (broad brush strokes using the traditional approach, ZBB within a department budget?)
