Reuse before buy/build

Digital services should demonstrate that they have sought to reuse existing solutions before delivering new ones.

Where it is not possible to reuse an existing solution, off-the-shelf (commercial or open source) products should be considered. For open source products there should be an appropriate level of contractual support provided. 

Only having ruled out the former two options should a new solution be built, either in-house or through third parties.

Summary

Digital services should demonstrate that they have sought to reuse existing solutions before delivering new ones.

Where it is not possible to reuse an existing solution, off-the-shelf (commercial or open source) products should be considered. For open source products there should be an appropriate level of contractual support provided. 

Only having ruled out the former two options should a new solution be built, either in-house or through third parties. 


Rationale

Reusing existing solutions will:
  • reduce cost and time to market

  • promote sustainability

  • reduce carbon footprint


Implication

Services should:
  • conform with the approved Technologies List, owned and managed by AIDA

  • use platforms

  • have their business case evaluated by technical and enterprise architecture

  • have their high-level solution architecture and risk log assessed by Architecture Approval Group
