Design Models.
After twenty-five years of delivering and observing different development models, these are the three most powerful tools I recommend for transforming your development practice.

Design Thinking
A practical set of tools to identify the core problem facing your users and generate ideas that really work in practice.
Design Thinking has a razor-sharp focus on the problem definition and unleashes creativity and out-of-the-box thinking in the design of solutions.

Cultural Theory
How do our models end up so far off, and why do we consistently overestimate project results or behaviour change?
Cultural Theory shows how our cultural lens makes some aspects of reality seem
illogical or invisible.
Understanding your own cultural bias and how others see things changes everything.

Micro TOC
Theory of change so often leaves the most crucial part out.
How will the proposed activity actually lead to the outcomes you want?
Micro Theory of Change focuses on the change mechanism from activity to outcome.
