Against the two-year roadmap
The two-year roadmap is the most reassuring document a programme produces and the least honest. Quarter eight is not a plan; it is a horoscope with a Gantt chart.
The problem is not ambition — keep the ambition. The problem is the precision. A roadmap that names deliverables eight quarters out is asserting knowledge nobody has: what the market, the organisation and the first six quarters of evidence will have done to the plan. In our audit work, the average two-year roadmap survives contact with reality for around five months; after that it is maintained as theatre, revised quarterly to keep the fiction continuous.
The theatre has a cost beyond the maintenance. Teams read long roadmaps as insulation — the deadline is far away, the sequence is someone else’s problem — and boards read them as certainty, which makes honest re-planning look like failure rather than learning.
Commit short, hold the ambition long
The alternative is not planning less; it is committing at the resolution knowledge actually has. The full ambition stays on the page as direction. Commitment — owners, baselines, dates — is issued one drawn phase at a time: three or fewer commitments, fourteen to fifty-two weeks, verified before the next phase draws. Beyond the current phase, the roadmap states intent, explicitly labelled as revisable.
The programmes that run this way in our data deliver more of their original ambition, not less — 71% against 22% at the extremes of concurrent load. Which is the quiet irony of the long roadmap: the document that promises the whole journey is the reason so many organisations never finish it.
