| Text | A major finding at StockIt's project retrospective was that different people in engineering had a different idea of what "ready" meant. Some developers thought the software was ready if it compiled. Some testers thought the product was ready when no more bugs could be found. Some managers thought it was ready when the ship date arrived. The project manager and the chief architect had their own definition of "ready" that was less one-sided. Unfortunately, the project manager and chief architect had not explained their criteria for each milestone. Without agreement on "ready" at the different milestones, the organization was in continuous disagreement about the state of the product and its readiness for testing and shipment. - "Managing Test Priorities for Packaged Software," Johanna Rothman |
