Choose tools and technology that let you build a good service in an efficient, cost effective way.
Build a sustainable service which allows you to change direction in future.
Detailed guidance of how to meet this standard can be found in DfE Architecture guidance (opens in new tab) and DfE Technical Guidance (opens in new tab).
Why it's important
When you make a decision about technology, you're making a significant investment. The choices you make will have a huge impact on your ability to create, iterate and operate the service in a flexible, sustainable way.
It's important to make sure you're not working on your own and use learnings from other teams or services where possible. Always try to align technology choices with other DfE teams. The more common components that are created and used the more efficient you can be in building a great service that meets the Service Standard.
When you make a decision about tools, look across DfE to see what's currently being used. Align with tools (opens in new tab) being used across other DDaT communities as much as possible.
How to meet this standard in every phase
You'll be assessed on what you've done to meet this standard at service assessments. However, even if the service you are working on is not being assessed, it's good practice to consider how you'll meet this standard point.
Things to consider:
- evidence that the team have considered different options to how the service will be delivered technically and the rationale for the chosen technical direction
- technology choices are technically feasible and security assured (opens intranet page in new tab). If you do not have access to DfE intranet, ask a colleague with access to get the information for you
- the tools the team will be using and why they are value for money
- how the tools and technology you choose meet accessibility standards , including Web Content Accessibility Guidelines (WCAG) 2.1 (opens in new tab)
- any constraints with legislation, contracts or technology that impact on the service
- align technology choices with the recommended tech stack (opens in new tab) used across DfE, where possible
- a working prototype, technical spikes, or proof of concept - using the chosen tools and technology - has been built and tested to prove that the architecture is fit for purpose
- architectural artefacts, decisions (opens in new tab) and plans have been documented, shared across your community and reviewed and assured
- evidence that the team will continue to re-evaluate and challenge previous decisions as new requirements are discovered
- demonstration that technology choices are sustainable (opens in new tab) longer term
