Will you replace our core system?
No, and you should be wary of anyone who opens with that. The core stays; the work is building around it so customers and staff get modern screens and the record of truth stays where it is. That means an integration layer that can absorb a core upgrade without the customer-facing product noticing.
What about the audit trail?
It is designed in from the start, because it cannot be added convincingly afterwards. Every action that touches a policy, a claim or a balance is recorded with who did it, when and what changed, and corrections are posted as new entries rather than edits. When a regulator asks why a decision was made, the answer should already be in the record.
How do you handle a system that can only be changed twice a year?
By putting the fast-moving work outside it. Customer-facing screens, document generation and reporting can change on their own schedule if the boundary is drawn properly, while the core keeps its release calendar. Most of the frustration in this sector comes from work being trapped inside a system that cannot move at the pace the business needs.
Can you work under our security review process?
Yes, and it is better to start there than to meet it at the end. Penetration testing, code review requirements, data residency and supplier questionnaires all shape the design, and knowing them at the outset costs a conversation. Discovering them at go-live costs a rebuild.
Our change freeze runs across year end. How does that work?
It gets planned for rather than argued with. Freezes cover the periods where the business cannot absorb a surprise, which for most institutions means year end, the statement run and any filing window, and they are the reason a delivery date here is set backwards from the calendar rather than forwards from an estimate. In practice, anything meant to be live before a freeze is finished and released with weeks to spare rather than days, work that would land during it is either configuration or held, and the fixes permitted mid-freeze are agreed in advance with a named approval route. A supplier who only discovers the freeze in November has already lost you a quarter, so we ask for the calendar in week one.
Do you copy production data into test environments?
Not without masking, and preferably not at all. Production copies are how customer records end up in environments with looser access and weaker monitoring, and they are one of the more common findings in this sector. Where realistic data is genuinely needed, for a volume test or a migration rehearsal, it is masked on the way out by a documented process, refreshed on a schedule, and held with the same access controls as production rather than the defaults a development team is used to. That has a cost worth stating: masked data breaks some referential rules and hides some real defects, so the awkward cases have to be built deliberately. It is still far cheaper than explaining a customer table sitting on a test server.
What access do your engineers have to our systems?
Named accounts, never shared ones, scoped to the work and removed when the work ends rather than when somebody remembers. Where you run privileged access management we use it, and where you do not, we would rather you did, because the alternative is a supplier account with standing rights that nobody reviews from one year to the next. We expect to be included in your access reviews and treated like any other group of users: the same joiner, mover and leaver process, the same evidence, the same removal on the day a person comes off the work. If it helps your review, we will write our own side of it down. It is a short document and it saves an uncomfortable meeting later.
Can you build a new product without touching the ledger at all?
Often yes, and it is usually the right first move. With the boundary drawn properly, quotation, pricing, document generation, servicing screens and reporting can all move at the speed the business wants while the ledger keeps its own release calendar. What cannot move outside is the record of value itself, and attempts to hold a second balance somewhere friendlier are how institutions end up with two numbers and a reconciliation nobody asked for. The rule we work to is that one place holds the money and everything else asks it. Where a product genuinely needs a change inside the core, we scope and price that as core work rather than smuggling it into a portal project and discovering it in testing.
