The question is directed to the existence of intangible factors that could explain the success or failure of a process of continuous improvement. Do you have any experience or know of previous work to develop this theme?
Here are some other intangible and soft factors that influence the success of LSS and CI processes:
1. Recognizing individual as to their importance to teams (i.e. acknowledge their technical expertise and value to the team)
2. Training of team members in the importance of team work (i.e. the synergy from working together)
3. Equitable assignment of action items allowing employees to get more control of their work processes and regular work assignments.
4. Ensuring management attends the initial/team launch session to explain "why" the need for this team and "Why" now.
5. Ensure management keeps engaged in the project through sponsorship, meeting attendance, show of continued support, reinforcement of importance of project - not relying entirely on technology for team updates (emails, sharepoint, etc.)
6. Providing team members with a standard approach for planning, implementing, executing and sustaining improvement, as well as the necessary supporting resources.
7. Management sponsorship, sponsorship, sponsorship and sponsorship.

For example, interaction of two factors whether they affect the response decides about choosing the model for experiment. This technique can be applied successfully to bothe process and products.
