Summary
Project management is both an art and a science, requiring a balance of technical skills (like planning and budgeting) and soft skills (like leadership and communication). The project manager’s role is critical to the success of any project, as they are the central point of coordination and accountability.
The role of a project manager is to plan, organize, lead, and control all aspects of a project to ensure it is completed on time, within budget, and meets its objectives, while effectively managing resources, risks, and stakeholder communication.
Whether you’re a student, a professional, or simply someone who wants to be more organized and efficient, understanding the principles of project management can help you succeed.
The PMI (Project Management Institute) defines project management as “the application of knowledge, skills, tools, and techniques to project activities to meet the project requirements.”
In simpler terms, it’s about using your resources and expertise to make sure you reach the goal of your project.
The PMI also defines a project as “a temporary endeavor undertaken to create a unique product, service, or result.”
This means that every project has a clear beginning and end, and it aims to produce something new or different.
Whether you’re building a skyscraper, developing a new software application, or simply planning a birthday party, project management helps ensure that your efforts are focused, efficient, and successful.
Without management, projects can easily become chaotic, resulting in missed deadlines, cost overruns, and even complete failure.
Project Management Triangle
The project management triangle, also known as the triple constraint, is a visual representation of the three fundamental constraints of any project: time, cost, and scope. These three constraints are interconnected, and changing one will inevitably affect others.
Time: The time constraint refers to the project’s schedule and deadlines. To meet the time constraint, you need to allocate sufficient time for each task and manage the project timeline effectively.
Cost: The cost constraint refers to the project’s budget. To manage costs, you need to estimate expenses accurately and track spending throughout the project lifecycle.
Scope: The scope constraint refers to the project’s goals and objectives. To define the scope, you need to establish clear boundaries for the project and what needs to be accomplished.
In addition to the three primary constraints, there’s a fourth element that’s often considered to be at the center of the triangle: quality. Quality refers to the project’s ability to meet the required standards and fulfill its intended purpose.

The project management triangle is a valuable tool for understanding the trade-offs involved in any project. By carefully balancing the three constraints and keeping a close eye on quality, you can increase the likelihood of achieving your project goals while staying within budget and on schedule.
The Project Manager
A project manager maps out the entire project. They figure out what needs to be done, who’s going to do it, and when it needs to be finished.

Examples
- A project manager leads a team developing a new mobile app. They define the app’s features, set deadlines for each development phase, allocate tasks to developers and designers, monitor progress, and test the app to ensure it meets user requirements. They also manage changes in scope, such as adding new features requested by stakeholders.
- A project manager leads a team launching a new product campaign. They develop a project plan, assign tasks to designers, copywriters, and social media managers, track the campaign’s progress, and ensure it stays within budget. They also analyze the campaign’s performance and report results to stakeholders.
- A project manager implements a new electronic health records (EHR) system in a hospital. They work with IT specialists, doctors, and administrators to define requirements, train staff, and ensure the system is rolled out smoothly. They also manage risks, such as data migration issues or resistance to change from staff.
