HEdway Adapted Double Diamond

Delivery method

The HEdway framework for delivering people centred change:

  1. Always start with people
  2. Co-diagnose the problems
  3. Co-create the solutions

Tailor the approach to the nature of the problems and opportunities; choose tools purposefully to match the need.

Diagram: HEdway delivery method adapted Double Diamond. A two-diamond model, Problem (Discover and Define) then Solution (Develop and Deliver), crossed with a vertical axis from naturally complex problems at the top to artificially complex problems at the bottom, giving recommended approaches, tools and management styles for each quadrant. The full content is described in text below the image.

The method in text

  1. Overarching double diamond framework: the Problem diamond opens with Discover and narrows through Define; the Solution diamond opens with Develop and narrows through Deliver.
  2. Match the delivery approach to the nature of the problem.
  3. Know what each tool is good for, and apply it purposefully.
  4. Manage lightly whenever possible, adding to it if needed.

Matching approach to problem

Naturally complex problems (no single right answer)

In the Problem diamond: a Systems Thinking approach, with tools such as Rich Pictures, the Iceberg model, Stocks and Flows, and Causal Loop Diagrams, managed with Project Light or Agile. In the Solution diamond: a Design Thinking approach, with tools such as Personas, Journey Maps, Empathy Maps, "How might we" questions, Prototyping and Pilots, managed with OGSM or MSP. Example applications: operating models, service architecture, policy development, culture change, and new digital services.

Artificially complex problems (solvable with the right tools)

In the Problem diamond: a Continuous Improvement (DMA) approach, with tools such as Voice of the Customer, SIPOC, process maps, the wastes, value-added analysis, 5 Whys and waste measurement, managed with Project Light or Agile. In the Solution diamond: a Continuous Improvement (IC) approach, with tools such as SECAR, One Best Way, FMEA, 5S, skills matrices, visual management and QCD, managed with PDCA or Agile. Example applications: process, data, operational and systems improvement, and existing digital services.
