The concept developed at ASEA, Johnson Line, Bolider Munktell and at Volvo. In Boston, USA the consultants "SMC Hendrick Inc." in the 1980s helped several large companies, like Burlington and John Hancock, build their total list of activities. Experience tells that the best activity list is made by the people doing the activities. Each part of the business can handle their own. Making their activity list is also an excellent opportunity for the people to create togeather and to get an understanding for what the others are doing at work. So as a spin off you get a smoother working group of people in each part of the business.
