Why IT needs lean by Operae Partners

This document outlines the typical IT project process and identifies issues with it. It involves multiple rounds of development, testing, and checks with the customer as requirements often change. This leads to bugs being found late in the process, requiring going back to development or specifications. As a result, teams like developers, testers, and incident managers become overloaded. The document suggests taking a lean approach to address these issues.
