Goal Tree, what for?

  • How Goal Tree can help Hoshin Kanri? A Goal Tree (Theory of Constraints / Thinking Processes tool) can help to define the required breakthroughs for strategic planning that Hoshin Kanri (Lean tool) will help to plan and cascade
  • A Goal Tree as vehicle for change management explains how the logical analysis of the actual situation and building the desired future condition with all stakeholders prevents resistance to change

Goal Tree chronicles

This series is about my own experience and lessons learnt with Goal Trees

  • Goal tree chronicles – What is our Goal? Business unit top managers unable to state the purpose of their unit, hence to define a Goal
  • Goal Tree chronicles – What are our CSF? Executives sharing a goal but unable to state the underlying Critical Success Factors
  • Goal Tree chronicles – The pharma plant A story about 20+ alleged strategic streams to manage
  • Goal Tree chronicles – ToC is about focusing! How Goal Tree and Hoshin Kanri would have helped pharma plant
