Make Scenario Development in St Davids
Building Make scenarios for St Davids organisations, where iterators and aggregators are where most of them go wrong. Splitting a list into separate items and recombining the results afterwards is the pattern people get subtly wrong — modules run more often than expected, results arrive in an unexpected shape, and the cost multiplies quietly.
Why this comes up
The problem
An iterator splits every order into line items and the following module now runs eight times per order.
What you get
What we deliver
- Iterators used where per-item processing is genuinely needed, not by habit
- Aggregators placed correctly so results recombine into the expected shape
- Operation cost per run understood, since iterating multiplies every later module
- Bundles traced through the scenario so the data shape is known at each step
- Filters applied early, before expensive modules rather than after them
- Array handling tested with empty, single and large inputs

Make Scenario Development in St Davids — common questions
- Why do iterators multiply cost?
- Because every module after one runs per item. An order with eight lines means the following steps execute eight times, so a scenario that looked inexpensive on a single record becomes considerably more so on a realistic one — which is easy to miss when testing with small data.
- When is an aggregator needed?
- Whenever the following step expects one thing rather than many. Iterating then failing to aggregate sends separate requests where one was intended — creating several records, several emails or several API calls instead of the single result somebody expected.
- Where should filters go?
- As early as possible. A filter placed after the expensive modules has already paid for them, whereas one immediately after the trigger discards irrelevant records before anything costly runs — which on a high-volume scenario is the largest saving available.
- What should be tested?
- The edges, particularly empty. A scenario built against an order with several lines behaves differently when one arrives with none, and an empty array flowing into an iterator is a common cause of scenarios that appear to do nothing at all.
- Do you work with businesses across Pembrokeshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including St Davids and the surrounding Pembrokeshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of St Davids businesses do you usually work with?
- Simple booking and payment systems for very small hospitality and tourism operators on the Pembrokeshire coast. Beyond that we work across Tourism & Heritage, Hospitality, Agriculture, Marine and Retail.
- Do you cover the areas around St Davids?
- Yes — we work throughout Wales, including Swansea, Cardiff. St Davids is an urban area of roughly 1,600+, and we take on work across the wider Pembrokeshire region rather than the city boundary alone.
