Software being developed and a business being ready to use it are two different stages. The point of a turnkey approach is to close the gap between them. When the content of delivery is visible from early in the project, last-minute uncertainty is reduced.
01Define the installation target from the start
Where the software will run affects development decisions. At Paradigma7, alongside our hosting infrastructure in Vienna, we also consider installing on a customer server that meets the technical requirements. The domain, external service access, and installation responsibilities should be spelled out in the project plan. Hosting location and company headquarters are two different things — Paradigma7 is headquartered at Ankara Next Level.
02Run acceptance with real transactions
Showing that pages load isn't enough at the delivery review. Creating a sample record, editing it, checking permissions, and completing the related workflow all need to be examined together. What the user sees in failure cases should be checked too. If a record is lost when the connection drops, for instance, having shown the successful flow doesn't make up for that gap. We covered how acceptance scenarios are prepared in our professional testing article.
03Make operational knowledge part of the delivery
The business needs to know where to change a given setting and how to share information when something goes wrong. Admin access, usage instructions, responsibilities, and agreed technical documentation all belong on the delivery list. Source code, licenses, infrastructure costs, and third-party subscriptions should be matched explicitly against the scope in the contract — the word "turnkey" alone doesn't settle their terms.
04Separate bug fixes from new development
At Paradigma7 we provide a 12-month bug-fix warranty from delivery. A deviation between delivered scope and expected behavior is a different kind of work from a new module requested afterward. Evaluation gets easier once the transaction where the issue occurred and the expected result are recorded clearly. New features and scope expansions are planned separately. We explained the difference between the warranty and annual maintenance in our annual maintenance agreement article. In our custom software service we write out the delivery scope together at the start of the project.
05Delivery package checklist
- Is the installation environment and its owner clear (Vienna infrastructure or a customer server)?
- Who holds the domain, email, and external service access?
- Have acceptance scenarios, including failure cases, been tested with real transactions?
- Have admin access and usage instructions been delivered?
- Do the source code, license, and third-party subscriptions match the contract?
- Is the channel and format for reporting bugs clear?
