Organisations rolling out multiple similar sites - retail chains, bank branches, warehouse networks - face a genuine structural choice in how they resource project management across the rollout, and the two dominant models trade off cost against consistency in noticeably different ways.
| Model | Typical cost | Typical consistency across sites |
|---|---|---|
| Dedicated PM per site | Higher total cost - full PM overhead multiplied across every site | Higher per-site attention, but risk of inconsistent standards/approach between different PMs across the portfolio |
| Shared regional PM pool (each PM manages multiple concurrent sites) | Lower total cost - PM overhead amortised across more sites | Requires strong standardisation (templates, checklists, standard specifications) to maintain consistency; without it, quality can vary by which sites get more attention from a stretched PM |
What Actually Determines Which Model Works Better for a Given Rollout
Rollouts with highly standardised site designs - a retail chain reusing the same fit-out template repeatedly - are genuinely well suited to a shared regional pool model, since the standardisation itself does much of the consistency work that would otherwise need to come from dedicated per-site PM attention. Rollouts with meaningful site-to-site variation - different building conditions, local approval processes varying by jurisdiction - benefit more from dedicated per-site attention, since each site genuinely needs individualised judgment a stretched shared PM may simply not have bandwidth to provide.
A Scenario Showing Why a Hybrid Approach Increasingly Wins
Picture a rollout programme combining a shared regional PM pool with strong centralised standards, templates and quality control oversight, rather than relying purely on either model in isolation. This hybrid captures much of the shared pool's cost efficiency while mitigating its consistency risk through the centralised quality control layer, which is precisely why this combined approach is increasingly the practical default for well-run rollout programmes rather than organisations choosing one pure model or the other.
