What does 'manage by stages' refer to in project management?

'Manage by stages' in project management refers to the practice of checking progress and making evaluations at defined set points during a project. This approach allows project managers to assess how well the project is adhering to its timeline, budget, and quality specifications. By splitting a project into stages with clear milestones, teams can make informed decisions based on the actual performance and outcomes of previous stages. This systematic monitoring and control help in identifying any issues early on and provides opportunities to make necessary adjustments before moving on to subsequent stages. This process not only enhances project transparency but also increases the likelihood of overall success by ensuring that all aspects are well-coordinated and efficiently managed throughout the project lifecycle.
