What is EA Light?

Enterprise Architecture Light (EA light) is a method that has been developed to allow organisations to quickly apply enterprise architecture techniques. It helps the organisation to develop an ICT strategy and quickly reap the benefits of enterprise architecture. It adopts some of the principles of agile programming practice:

  • It places trust in the skills of the individual allowing them to document decisions quickly and simply.
  • It emphasises individual communication over documented communication with customer and colleagues.
  • It believes in the importance of sharing information widely and freely within the organisation.
  • It is focussed on productivity over method. In this case, productivity is measured in the making and recording of organisational and architectural strategic decisions.
  • It supports self-organising teams providing space within an overall governance process for them to do architecture their own way.
  • It is designed to cope rapidly and well with change supporting continuous delivery of strategy.

As with all enterprise architecture, EA Light delivers a wide range of benefits to the customer. However to provide some examples EA Light can help with:

  • Planning integration and interoperability strategies;
  • Planning and costing large and complex releases and transitions;
  • Supporting organisational and system change;
  • Introducing a methodical governance of the ICT landscape;
  • Aligning disparate supplier systems or (agile) delivery functions with strategy;

The ultimate aim of EA Light is to provide a comprehensive ICT Strategy. Its light touch approach means it is particular suitable at delivering strategies across very large landscapes where total access and control over the disparate parts is not always possible.
