Backwards mapping

Most planning starts with what you will do first. Backwards mapping does the opposite: it starts with the destination and works backwards to figure out everything that has to be true along the way to get there.

The workbook's own words, describing how a Theory of Change is built: it is "a step-by-step, backwards mapping process through which all project activities determine all the preconditions necessary to reach an ultimate vision."

The logic is simple once stated. If you know where you want to end up, you can ask: what has to be true just before that? Then: what has to be true before that? — and keep going until you reach where the project actually starts.

Backwards mapping is the method, not the end product — the end product it builds is the causal pathway.

The workbook's Theory of Change process (section 6.1.1) begins with situation analysis, identifying the problem the intervention addresses, and gathering relevant information on inputs, outputs, outcomes and impact from both primary sources (stakeholder feedback) and secondary sources (published research and documents).

From there, backwards mapping works in the reverse direction from how a project is usually described day to day:

1. Start with the ultimate vision — the long-term goal the project exists to reach.
2. Ask what preconditions must hold immediately before that vision is achieved.
3. Work backwards through each earlier precondition, one link at a time, until the chain reaches the project's actual starting activities.

Because the process works backwards, it also surfaces contextual factors that help or hinder the change — and the assumptions the whole chain depends on — as a natural by-product of asking "what has to be true here?" at every step.

Illustrative example.

A non-profit wants to raise literacy rates among out-of-school children in a slum cluster. Working backwards from the vision:

Vision: 90% of enrolled children read at grade level within 3 years. Step back: Children attend school regularly enough to complete the curriculum. Step back: Parents allow and support daily school attendance. Step back: Parents see a clear enough benefit from schooling to prioritise it over immediate household needs. Step back: A livelihood-support or stipend component exists to offset the opportunity cost of a child not working.

Backwards mapping surfaces the stipend component as a precondition the project team might not have identified if they had only planned forwards from "open an after-school reading class." Planning forwards, the reading class looks sufficient; planning backwards from the vision reveals a household-income precondition the reading class alone cannot satisfy.

Chapter 6, section 6.1.1 (Theory of Change), describes backwards mapping as the defining method by which a Theory of Change is constructed. Expect a question asking which direction Theory of Change planning runs (from the ultimate vision backwards to preconditions), contrasted with the more linear, forward-running structure of a Logic Model.

• Backwards mapping runs from the vision back to preconditions — not forwards from activities to outcomes, which is how a Logic Model is more typically read.
• This is the method that produces a causal pathway — the two terms are related but not identical; do not use them interchangeably in an answer that specifically asks for the method versus the result.
• Backwards mapping is specific to Theory of Change, not a general planning technique applied across every framework in this workbook.
• A precondition identified through backwards mapping is not automatically an assumption — a precondition is a step that must be achieved; an assumption is an external condition the pathway depends on being true, though the two often surface together.
