Step-by-step explanation:
Under project planning activities, defining what leads to successful completion is a part of goals and objectives. The process of defining goals and objectives is crucial as it sets the target for what the project aims to achieve and guides the entire team towards a unified end result. Establishing clear, achievable and appropriate goals is a fundamental step in ensuring the project's success. This is because once goals are set, they dictate the planning of strategies and methods to attain them, influencing the decision-making process throughout the project's life cycle.
For instance, during the development of a new product design project, a significant amount of time is dedicated to the development of a detailed design from a concept. If the detailed design is not well-thought-out, it can negatively impact the project, undermining even a strong conceptual foundation. Hence, setting focused and well-defined objectives early on can save time and resources while enhancing the likelihood of project success.
