The business strategy of the organization is the preliminary input to the EA metrics model consisting of EA Metrics inputs and EA planning inputs. Use these inputs in all planning activities across the organization. Measuring the planning effectiveness and efficiency would clearly represent the value of EA to business, as these planning activities affect all four aspects of the organization, i.e. customer, finance, growth and processes.
Customer metrics: Focus is on increasing the business value using EA. It helps in improving the business process (quality, costs) efficiency through architecture initiatives. Also, improves the business and IT alignment.
Financial metrics: It covers capital expense reduction through the prevention of non-standard, one-off solutions. It helps in enabling the organization to use the latest technologies and asset reuse. Promotes operational expense reduction in the form of supporitng rationalization to simplify the portfolios, which brings cost transparency to run IT.
Growth metrics: Focus on collaboration, workforce effectiveness, learning and capability factors.
Process metrics: Regulatory compliance and project architecture assurance are covered as part of this metric. It drives behaviors toward adopting relevant IT standards & complying with processes. Also, it helps in improving collaboration through stronger compliance with IT standards and processes.
The Metrics types are:
Short term: These metrics measure the progress of EA during the initial iterations of EA implementation.
Long term: These metrics measure the efficiency and effectiveness of EA to ensure that the true value of EA is delivered to the business.
Establishing an Enterprise Architecture function helps organizations keep complexity and misalignment at bay. However, it is not inconceivable that Enterprise Architecture may itself fall prey to this complexity trap if it is not well defined, managed and maintained. Even if it is, it may be of little to no value to the organization if the well-defined artifacts are not in use by the organization or if the EA processes not adhered to.
To ensure that Enterprise Architecture is progressing well and is adding value to the organization, there is a need to define metrics for measuring the progress and performance of EA.
The EA metrics should measure the implementation of EA and be governed by the concept of EA maturity. EA metrics should be defined in terms of effectiveness, agility and alignment to business goals and strategies. Once EA architecture is properly implemented and business entities are engaged, it will improve the overall planning activities of the organization and not just IT.
