SYSE.1:5 - Archetypal Grounding
Pumping station under flood risk
A flood-reduction project starts with the phrase “new pump”. The engineer compares the pump unit, the pumping station, the drainage-control System, and a provider arrangement. Flood-control use crosses the pump-unit boundary: positioning, power, control, discharge conditions, and downstream exposure belong to the station’s current use question. The engineer selects the pumping station and records:
selected referent: intended pumping station
current reason: move water under the selected flood load as part of flood-control use
main unresolved assumption: downstream exposure remains acceptable
reopen: use, architecture, realization, or operating evidence changes that assumption or boundary
SYSE.2 can now link the flood-load use claim to a station concept.
Later discovery that the proposed station increases downstream harm changes the linked use claim. It reopens
the project-system choice only when that changed claim defeats the reason or boundary used by the choice account.
Manufacturer and ERP vendor
A manufacturer opens a “new ERP” project because production plans repeatedly fail. The manufacturer compares the software product, the planning organization, a deployed planning System containing people, software, data, and decision interfaces, and the wider production-control System. It selects the intended deployed planning System because the current project changes production-planning use and records data quality as the main assumption.
The vendor’s product project can separately select the ERP software product. “Software is always the project system-of-interest” and “software is never the project system-of-interest” both erase the project-specific decision. The two accounts preserve the shared software and the different uses.
Continuing building through several projects
For example, design, construction, operating retrofit, and heritage-restoration Work can concern one continuing building while using different plans, transformer Systems, access arrangements, and evidence. In an occupied retrofit, the engineer selects the continuing building because its occupied performance is being changed and records access during use as the main unresolved assumption.
Several descriptions of the building do not create several Systems or projects. Conversely, one programme does not become the performer of all Work. Each project account states its own reason for selecting the building and can reopen that choice without inventing a birth-to-retirement order.
