Enterprises have accepted that they must take a blended approach to enterprise architecture, according to the latest report from Gartner.
The analyst firm said that around 95 per cent of companies will support a " multiple approach" to their architecture by 2015.
"Businesses are realising that there is no one way to support enterprise architecture," said Julie Short, research director at Gartner.
"The key is to create, not the perfect or most elegant architecture for the moment, but the most adaptable architecture for the future."
Organisations have four options for enterprise architecture - traditional, federated, middle-out and management diversity - and will support a mixture of them all, according to Gartner.
"The reality is that most organisations do not apply a single approach to enterprise architecture in a pure form," added Betsy Burton, vice president and distinguished analyst at Gartner.
"Rather, they use a number of different approaches in different areas, resulting in a blended reality that truly meets the needs of their business."
Gartner defines the traditional approach as that in which the enterprise architecture team works closely with the rest of the business on its plans. This works best in firms where decision making is largely centralised and change-averse.
A federated approach works best in companies where decision making is decentralised, and would suit organisations with distributed offices. Gartner said that this is often seen in firms after merger or acquisition.
Managed diversity suits enterprises that have a lot of project teams, or silo groups, that may need to set their own requirements. But Gartner said that a disadvantage is that users and project teams must take responsibility for their choices.
The final part of the mix is the middle-out approach in which one group creates a small set of enterprise architecture standards, but farms out the specifics to the departments responsible for using them.
Gartner said that any enterprise architecture teams within an organisation should determine what it called a "decision framework" which will let them evaluate which approach is most suitable.
