What are responsibilities of the project manager during the implementation phase?

A project manager is a person who has the overall responsibility for the successful initiation, planning, design, execution, monitoring, controlling and closure of a project. Construction, petrochemical, architecture, information technology and many different industries that produce products and services use this job role.

Watch What Does a Project Manager Do?

A project manager must have a combination of skills, including asking penetrating questions, detecting unstated assumptions, resolving conflicts, and possessing good general management skills.

The critical areas controlled by a project manager are scope, schedule, resources, finance, quality and risks.

Key among a project manager's duties is recognising that risk directly impacts the likelihood of project success and that this risk must be formally and informally measured throughout the lifetime of a project.

Risks arise from uncertainty, and the successful project manager is the one who focuses on this as their primary concern—most of the issues that impact a project result in one way or another from risk.

A good project manager can lessen risk significantly, often by adhering to a policy of open communication, ensuring every significant participant has an opportunity to express opinions and concerns.

A project manager is a person who is responsible for making decisions, both large and small. The project manager should make sure they control risk and minimise uncertainty. Every decision the project manager makes must directly benefit their project.

A project manager may use project management software, such as Basecamp, Wrike and Asana (many other solutions are available) to organise their tasks and team. These software solutions allow project managers to orchestrate their work and produce reports and charts in a few minutes, compared with the several hours it can take to create them by hand using office software.

  • Planning and Defining Scope
  • Activity Planning and Sequencing
  • Resource Planning
  • Developing Schedules
  • Time Estimating
  • Cost Estimating
  • Developing a Budget
  • Documentation
  • Creating Charts and Schedules
  • Risk Analysis
  • Managing Risks and Issues
  • Monitoring and Reporting Progress
  • Team Leadership
  • Strategic Influencing
  • Business Partnering

Some of the techniques a project manager will find helpful in their daily work are:

  • Earned Value Management
  • MoSCoW Method
  • Pareto Analysis
  • PEST Analysis
  • RACI Model
  • SWOT Analysis

Finally, senior management must provide support and authority for a project manager if they will be successful. Without this support, a project manager will likely struggle, and projects become delayed and, in the worst cases, fail.

“A project manager is like a doctor who leads the trauma team and decides the course of action for a patient - both at the same time. Without the right kind of authority to efficiently handle all the project management issues, development teams can easily get into trouble.” - Scott Berkun, the author of “Making Things Happen”

How did it all start? In the late 1980s, Microsoft was launching an ambitious project and had run into a problem: there were way too many players involved. There were teams from marketing, engineering, and the business end, and no one knew how to coordinate all of them.

So, Microsoft came up with what was then an ingenious solution. They picked one person to take charge of who would be given significant authority to organize and coordinate their new project. Once Microsoft appointed a dedicated leader, everything went smoothly and the teams were much happier with their work dynamics. The end result of this new strategy was Excel.

Eventually, Microsoft made this new role as a staple for all their projects. Thus, the project manager was born.

8 key roles and job responsibilities of project managers

At the end of this post, you'll find a cheat sheet containing an overview of a project manager's key responsibilities! But first...

WHO are project managers and what are they like?

Good project managers are people with an excellent entrepreneurial mindset. This allows them to think about a project beyond the basic skill set needed to manage it, and it is the project manager’s job to direct teams and team members to the finish line. At the end of the day, the project’s success or failure rests solely on the project manager’s shoulders, and he or she is the one responsible for the end result.

Project managers keep knowledge and information flowing seamlessly. They need both technical know-how and first-hand knowledge of the tasks they assign to others to keep the project moving forward.

"Project Managers play the lead role in planning, executing, monitoring, controlling, and closing projects. They're expected to deliver a project on time, within the budget, and brief while keeping everyone in the know and happy."

But technical know-how does more than enable project managers to communicate ideas effectively to all those involved. Good project managers use their technical understanding to win team members’ respect. Since project managers influence more decisions than anyone else in the company, their primary task is to use what they know to not just win employees’ respect, but keep it throughout the project and into the future.

What do project managers DO? 8 key roles and responsibilities

1. Activity and resource planning

Planning is instrumental in meeting project deadlines, and many projects fail due to poor planning. First and foremost, good project managers define the project’s scope and determine available resources. Good project managers know how to realistically set time estimates and evaluate the team's or teams’ capabilities.

They then create a clear and concise plan to both execute the project and monitor its progress. Projects are naturally unpredictable, so good project managers know how to make adjustments along the way as needed before the project reaches its final stages.

2. Organizing and motivating a project team

Good project managers don’t get their teams bogged down with elaborate spreadsheets, long checklists, and whiteboards. Instead, they put their teams front and center. They develop clear, straightforward plans that stimulate their teams to reach their full potential. They cut down on bureaucracy and steer their teams down a clear path to the final goal.

What are responsibilities of the project manager during the implementation phase?

"There is no other way than leading by example. If you are doing your part correctly, always supporting your team, and having a fair and healthy approach with them, motivation should never be a problem."

3. Controlling time management

Clients usually judge a project’s success or failure on whether it has been delivered on time. Therefore, meeting deadlines are non-negotiable. Good project managers know how to set realistic deadlines, and how to communicate them consistently to their teams.

What are responsibilities of the project manager during the implementation phase?

They know how to effectively do the following:

  • Define activity
  • Sequence activity
  • Estimate the duration of activity
  • Develop a schedule
  • Maintain a schedule

4. Cost estimating and developing the budget

Good project managers know how to keep a project within its set budget. Even if a project meets a client’s expectations and is delivered on time, it will still be a failure if it goes wildly over budget. Good project managers frequently review the budget and plan ahead to avoid massive budget overruns.

5. Ensuring customer satisfaction

In the end, a project is only a success if the customer is happy. One of the key responsibilities of every project manager is to minimize uncertainty, avoid any unwanted surprises, and involve their clients in the project as much as is reasonably possible. Good project managers know how to maintain effective communication and keep the company’s clients up-to-date.

6. Analyzing and managing project risk

The bigger the project is, the more likely there are to be hurdles and pitfalls that weren’t part of the initial plan. Hiccups are inevitable, but good project managers know how meticulously and almost intuitively, identify and evaluate potential risks before the project begins. They know how to then avoid risks or at least minimize their impact.

What are responsibilities of the project manager during the implementation phase?

"You have to go in expecting that things won't be as you had planned, and things won't be as easy as first expected. Goals, conditions, and circumstances will change."

7. Monitoring progress

During the initial stages, project managers and their teams have a clear vision and high hopes of producing the desired result. However, the path to the finish line is never without some bumps along the way. When things don’t go according to a plan, a project manager needs to monitor and analyze both expenditures and team performance and to always efficiently take corrective measures.

8. Managing reports and necessary documentation

Finally, experienced project managers know how essential final reports and proper documentation are. Good project managers can present comprehensive reports documenting that all project requirements were fulfilled, as well as the projects’ history, including what was done, who was involved, and what could be done better in the future.
