[Service Standard] Use open standards and common platforms

[jukesie]

To pass your alpha assessment, you usually need to explain how you:

use open standards and common platforms to avoid getting locked into contracts

use common platforms for your system, such as GOV.UK Verify as an option for identity assurance

identify the common user needs your service meets and what you reuse from across government to help meet those user needs
