5. Evaluate what tools and systems will be used to build, host, operate and measure the service, and how to procure them, looking to reuse existing technologies where possible.

The purpose of this point is to make sure that thought is given to the most suitable tools and systems used to develop, operate and measure the service.

As technology develops so quickly it is important that the tools and systems chosen are future-proofed, flexible and scalable enough to not only meet current requirements and demands, but also anticipate future requirements and demands. Thought should be given to ensuring that systems can handle peaks in demand, be they seasonal or specific event driven.

The technologies chosen should be the best fit based on the requirements of the user/service and offer the best value for money. Consideration should be given to the technology and architecture already in place, looking to re-use existing technologies where possible. Insight should be gained from other organisations that are running similar services to see if common technology can be used or services/technology shared.

There are some further guidelines to help in the choosing technology section of the Government Service Design Manual


The Standard was launched on 7 April 2016.
