Earned Value Management

(EVM) is a project management technique that uses scope, schedule, and cost data to assess a project’s progress and performance. It integrates scope, schedule, and cost measures to provide a comprehensive view of the project’s health. EVM compares the planned work with the actual completed work and the actual costs incurred, offering insights into both the status and future projections of the project.SELF-PACED ONLINE TRAINING COURSESThe key components of EVM are:Self-paced online training courses (e-learning) include:Planned Value (PV): The budgeted cost of work scheduled to be doneCertification exam(s) where applicable

The three constraints of scope, time and cost are interconnected and can impact each other. Changes to one constraint will likely influence the other constraints. For example, an increase in scope will often require additional time and resources, whereas a reduction in time may increase costs or decrease scope. Similarly, a reduction in budget may affect the project scope or timeline. and AgileBA

Lean approachesPreferences

prioritise efficiency and cost control and are useful when budget is the main constraint. MarketingChoosing the right approach from the beginning aligns with the key constraints. Follow the tips above to help manage the project management triangle and balance constraints throughout your project. The most important thing is to continuously monitor and maintain alignment of the three sides. Assess the status of scope, time, and cost regularly to identify imbalances. Be willing to make informed decisions and trade-offs as necessary. And communicate clearly with stakeholders about any changes to plans or constraints.
