Why bimodal IT is terrible

What: "The False Promise of Bimodal IT," a report from Forrester Research.

Why: Bimodal IT is a system in which IT delivery is divided into separate agility- and stability-focused flows. But Forrester's report claims that what some CIOs see as a best-of-both-worlds compromise will only hamper organizational effectiveness.

The report lands amid comments by U.S. CIO Tony Scott in which he previewed upcoming guidance on using bimodal delivery at federal agencies with large legacy IT footprints.

Scott later clarified to FCW that he wasn't necessarily wed to any particular definition of "bimodal IT," but wanted to stress that, "[W]e've got a bunch of old stuff that we've got to manage our way out of, and have a bunch of modern approaches we will move to."

Forrester researchers say that by distancing IT decisions from the broader business, the approach threatens to isolate IT at a moment when technology has never been more integral to an organization's operations.

Its two-class setup would gut any quick-moving organizational culture, and it could enable agencies to allow badly outdated legacy systems to continue in the name of stability, the report warns.

Instead of bimodal IT, Forrester's analysts said organizations should pursue a customer- and data-driven, unified business technology approach.

Verbatim: "When the business needs simplicity-driven innovation, bimodal IT adds complexity with its siloed, two-class system around a fast and slow approach. It makes no sense to have two groups competing for funding, resources, skills and the business' attention."
