For each of the descriptions in Column 1, the maintainability objective from Column 2 that each would support is as follows:

Off-the-shelf software with ready-to-use templates that will need to be customised to fully meet Hoy Hall requirements, after deployment.

A. Maintainability is a required attribute of the initial delivered solution

Rationale: Customizing off-the-shelf software indicates a need for the solution to be maintainable from the onset to allow for these adjustments.

Developing a fully functioning in-house system, developed and hosted by Architecture Angels IT Operations team.

A. Maintainability is a required attribute of the initial delivered solution

Rationale: In-house developed systems need to be maintainable to facilitate future changes and enhancements by the team that created them.

All-in-one web-based reservation and accommodation management system built to Hoy Hall ' s specification.

A. Maintainability is a required attribute of the initial delivered solution

Rationale: A system built to specific requirements will require the ability to maintain and adjust the system as needs evolve, making maintainability a key initial attribute.

All bookings for Hoy Hall to be scheduled by one of the other two hotels within the group, until a suitable system can be implemented at the site.

C. Short-term, tactical solution

Rationale: This is clearly a temporary measure until a proper system is in place, indicative of a tactical solution to address immediate needs.

A spreadsheet is used to capture customer details manually. Data will then be exported into a fully functional system at a later date.

C. Short-term, tactical solution

Rationale: Using a spreadsheet is a stop-gap solution to manage information in the short term, emphasizing the tactical nature rather than long-term maintainability.

Option B is not selected for any of the descriptions as none of them imply an approach of delivering first with the intention to re-engineer later. They all suggest a need for immediate maintainability or a short-term fix, not a re-engineering approach.
