Drawing the scope boundary before anyone counts modules
Scope conversations usually open with a module list, because that is how licence quotations are structured. It is the wrong starting point. A module list says nothing about whether an order can be taken, priced, produced, delivered and invoiced without leaving the system, and that end to end path is what determines effort. We scope by process chain instead, then work backwards to the modules the chain implies. The list that emerges is often shorter than the one on the quotation, and occasionally longer in a place nobody expected.
Entity structure is the second dimension and it is routinely underestimated. Two legal entities in one country sharing a warehouse are a different problem to two in different countries with different tax treatment, statutory reporting and languages. Sites add a third dimension. Ask early how many plants, depots and sales offices will transact in the system during phase one, and how many are merely expected to follow later. The answer changes the design of almost everything above it, including the chart of accounts.
What gets excluded matters as much as what is included, so exclusions are written down with the same care. A deferred module, a report that stays in a spreadsheet for another year, an interface waiting on a counterparty who is not ready: each is recorded with a reason and a date to revisit. Teams that skip this spend the second half of the programme arguing about whether something was ever in scope. Written exclusions end that argument in a minute rather than a meeting.
- Scope defined as end to end process chains rather than a licensed module list
- Legal entity, country, currency and language count fixed before the chart of accounts is designed
- Sites transacting in phase one separated from sites merely expected to follow
- Exclusions written down with a reason and a date to revisit
- One named person on your side who can approve a change of scope
