Stage 1 : problem definition

  • Understand the initial situation
    • 5W2H (problem-oriented)
  • Quantify
    • Summary Table
    • Data visualization
  • Determine which problem is the most important
    • Pareto Diagram
  • Determine the problem to be solved
    • 5W2H

Fastest way to go is to use an data processing tool, e.g.

  • Excel/Google spreadsheet for data and graphics
  • Use screen capture with powerpoint
  • left clic/save image with powerpoint
  • insert/image here

please be clear about the message conveyed by each graphic

After analyzing these graphs, what are your conclusions ?

Selecting the ideas : Shortlist

What is are your quality criteria to determine the best solution amongst the final 6 shortlist ?

  • Your quality criteria : please fill in with your choices
    • cost
    • efficiency
    • alignment with strategy
    • ....
  • How do you weight each criterion ?
    • cost is a priority for us : weight is 3

Measurable : Measure / prove whether you are meeting the objectives, design progress indicators.

Accepted : How to get approval and go from all stakeholders, specify who will do what.

Realistic & ambitious : Be reasonable given available resources (the budget and manpower you asked for in phase 1)

Time-bound : Give milestones and date - when will results be achieved?
