What Is a Project Manager? What They Do, Skills, Salary Path and How to Become One

A project manager is the person responsible for planning, executing and delivering a project, a temporary piece of work with a specific goal, scope, budget and deadline, so that it achieves its objectives on time, on budget and to the required quality. They coordinate people, tasks, risks and communication, from kickoff to close. In short: the project manager makes sure the right work gets done by the right people at the right time.

Project managers work in almost every industry: construction, IT and software, marketing, healthcare, engineering, consulting, events, finance and government. This guide explains what a project manager does, the skills you need, how the role differs from similar titles, how to become one, why project management matters, and how AI and automation are changing the job.

What does "PM" mean?

PM most often means project manager (the person) or project management (the discipline). In technology companies, PM can also mean product manager, a different role (see below). And of course "p.m." also means post meridiem, the afternoon! Context tells you which.

What is project management?

Project management is the application of knowledge, skills, tools and techniques to deliver a project's objectives. It's typically organised into five phases (the Project Management Institute's process groups):

1. Initiating: define the project, its purpose and stakeholders; get approval.
2. Planning: define scope, schedule, budget, resources, risks, quality and communication.
3. Executing: coordinate people and resources to do the work.
4. Monitoring and controlling: track progress, manage changes, risks and issues.
5. Closing: deliver, get sign-off, release resources, capture lessons learned.

What does a project manager do?

Core responsibilities

• Define scope and objectives with stakeholders, and what's out of scope
• Plan the project: tasks, timeline, milestones, dependencies
• Estimate and manage the budget
• Assemble and lead the team; assign responsibilities
• Identify and manage risks, issues and dependencies (often in a RAID log; see What is a RAID log?)
• Communicate: status updates, stakeholder meetings, reports
• Manage changes to scope, schedule or budget through a controlled process
• Remove blockers so the team can work
• Ensure quality and acceptance of deliverables
• Close the project and capture lessons learned

A typical day

• Morning stand-up or check-in with the team
• Reviewing progress in the project tool and updating the plan
• Chasing blockers: a missing approval, a supplier delay, a resourcing conflict
• Stakeholder meeting to agree a scope change
• Updating the risk log and budget forecast
• Writing a weekly status report
• Planning the next phase

Project managers spend a large share of their time communicating: listening, aligning, negotiating, informing.

Key project manager skills

Hard skills

• Planning and scheduling (work breakdown structures, Gantt charts, critical path)
• Budgeting and cost control
• Risk management
• Methodologies: Waterfall, Agile (Scrum, Kanban), hybrid
• Project management tools: Asana, Jira, Monday.com, Smartsheet, Microsoft Project/Planner, ClickUp
• Reporting and data (dashboards, KPIs)
• Contract and vendor management

Soft skills

• Communication (written and verbal)
• Leadership and motivation without always having formal authority
• Stakeholder management and negotiation
• Problem-solving and decision-making under uncertainty

Project manager vs program manager vs product manager

Types of project managers

• IT / technology project manager: software, infrastructure, system implementations
• Construction project manager: buildings, infrastructure, site delivery
• Engineering project manager
• Marketing / creative project manager: campaigns, content, launches
• Healthcare project manager
• Agile project manager / delivery manager
• Implementation or professional services PM: delivering projects for clients (often using PSA tools; see What is PSA software?)
• Event project manager

Why is project management important?

• Delivers results: projects with clear goals, plans and ownership are far more likely to succeed.
• Controls cost and time: early visibility of overruns allows corrective action.
• Manages risk: anticipating problems rather than reacting to crises.
• Aligns stakeholders: everyone agrees what's being delivered and why.
• Uses resources efficiently: people work on the right things without overload.
• Improves quality: defined acceptance criteria and reviews.
• Builds organisational learning: lessons learned improve future projects.

How to become a project manager

1. Start managing projects in your current role

Many project managers start as "accidental project managers": they're the person who organises things. Volunteer to coordinate a project, launch, migration or event at work.

2. Learn the fundamentals

Study planning, scheduling, budgeting, risk management, stakeholder management, and both Waterfall and Agile approaches. Free and low-cost options include Google's Project Management Certificate (Coursera), PMI's free resources, and Agile/Scrum guides.

3. Get certified (optional but valuable)

4. Learn the tools

Get comfortable with at least one popular tool (Asana, Jira, Monday.com, Microsoft Project/Planner or Smartsheet) and with spreadsheets and presentation tools.

5. Build a portfolio of results

Document projects you've led: goal, your role, challenges, results (time saved, budget met, outcomes). Use these stories in interviews.

6. Target entry roles

Project coordinator, project administrator, PMO analyst, junior project manager, or associate PM roles are common stepping stones.

7. Develop domain expertise

Specialising in an industry (IT, construction, healthcare, marketing) makes you more valuable.

How AI and automation are changing project management

AI is taking over much of the administrative side of project management:

• Meeting notes and action items captured automatically and turned into tasks
• Status reports drafted from project tool data
• Risk detection: AI flags slipping tasks, overloaded people and dependencies at risk
• Scheduling and resource suggestions
• Natural-language project queries: "What's blocking the launch?"
• Automated workflows for approvals, reminders and handoffs
• AI agents that update plans, chase updates and prepare stakeholder communications

(See How to track tasks at work for practical automations.)

What AI doesn't replace: leadership, judgement, negotiation, trust-building and accountability. The project managers who thrive will use AI to eliminate admin and spend more time on people, stakeholders and decisions.

Not necessarily. Many project managers come from varied backgrounds. Experience, certifications and demonstrable results often matter as much as a degree, though some industries and employers prefer one.
