A major telecommunications equipment supplier faced a familiar problem: how do managers deliver consistent, repeatable results in a distributed environment? Our client needed to coordinate 20 sub-teams using differing estimation processes that were informal, undocumented, and could not be repeated when desired. Ad hoc processes produced unreliable estimates and products that were late, over budget, and buggy. The completed estimate was then loaded into SLIM-Control to manage project execution against the plan. When project actuals strayed into the yellow control region the team asked questions, identified the problem, and took immediate corrective action to get the project back on track. Calibrating SLIM-Control allowed them to sanity check various options against the team’s proven ability to deliver software. Because the tool made extensive use of their own historical data, the team felt confident in their projections and the SLIM-Control methodology. They even adopted the motto: “SLIM is always right!”
