Outsource Development: Risks of Underestimating Project Scope

In this article, an author with 20 years of experience in custom software development analyzes the critical issue of underestimating project scope in outsourcing. The focus is on projects with budgets ranging from 10 to 100 million rubles, where clients often miscalculate labor requirements by two or three times. Such errors at the start turn a project into a 'ticking time bomb,' leading to failure regardless of the chosen methodology. The author argues that even in modern conditions, detailed planning—characteristic of classical approaches like Waterfall or RUP—remains the only reliable tool for increasing forecasting accuracy. Despite the difficulty of formalizing requirements, deep specification work allows for achieving predictability within +-30%. The article calls for a more responsible approach to the launch phase, emphasizing that high-quality planning is the foundation for the successful implementation of any large-scale IT project.
