BigLever Software Customer Case Studies

Featured Case Study: Engenio Information Technologies

Problem: The demand for Engenio's storage server products was rapidly out pacing the firmware development team's ability to create, evolve and maintain the firmware for those products. Engenio concluded that a software product line approach posed many potential benefits; however, based on prevalent software product line publications, they anticipated a lengthy adoption cycle (900 to 1,350 developer-months) for transitioning their development efforts. 

Solution: Engenio selected BigLever to enable them to make an incremental transition into a product line practice. With BigLever, Engenio invested only four developer-months of effort upfront, and 12 developer-months overall, to incrementally transition 23 products, each comprising 1 million lines of code, and 135 developers to a software product line practice. This is less than 1% of effort previously reported for legacy software product line transition efforts.
