How IBM started grading its developers' productivity

By , Network World |  IT Management, IBM

IBM has plenty of application development tools at its disposal, including those from its own Rational software line. But tooling and process can only go so far to assure code quality.

"At the end of the day, people are in the middle" of application development, says Pat Howard, vice president and cloud leader in IBM's global business services division. "It's really important to have great investments, great energy focused around the talent."

Howard led application development at IBM, where he was responsible for delivering applications across all of Big Blue's brands and overseeing its global development teams. On the talent front, he helped implement a system for analyzing individual application developers based on the volume and quality of their work.

The core of the system is a commercial software product from Cast. The French vendor's automated software analysis and measurement platform provides metrics around the structural quality of application code and the performance of development teams.

Using the Cast platform, IBM managers can analyze how a developer pieces code together, for instance, and make a quantitative determination of the developer's abilities. The system can review the code's performance, security and technical depth -- gauging, for instance, whether the code going to have a lower cost of maintenance in the long term.

"If you're writing something in Java, is the code itself structured in a manner that is compliant with what is recognized as an industry best practice? That's the type of science that Cast helps produce," Howard says.

It's a quantitative analysis, rather than a subjective observation. [See also: "5 requirements for measuring application quality"]

In the past, it has been a challenge for IBM to manage application development talent in a way that's reliable and predictable, particularly since teams are scattered around the world, Howard says.

Plus, the demand on development teams is constant. Anytime IBM makes a change to the business -- an update to its supply chain, adding new salesforce capabilities, or preparing a new product release -- invariably there are application changes required.
