Management vs Leadership: What New Managers Need to Know

What Is the Difference Between Management and Leadership?

The short version: management is about doing the current work well, and leadership is about getting people ready and willing to do something different.

A manager makes sure the right people are on the right tasks, the work meets the standard, the budget holds and problems get fixed. A leader gives people a reason to care: where the team is heading, why it matters, and what part each person plays. One keeps the wheels on. The other decides where the vehicle is going and gets everyone to climb in.

Most of what you’ll read online treats this as a contest, with leaders cast as the visionaries and managers as the people with clipboards. That isn’t much use if you’ve just been made a team leader, because your job is both. On Monday morning you’ll be sorting a staffing gap (management). On Monday afternoon you’ll be explaining to a sceptical team why the way they’ve always done something is about to change (leadership).

What Did John Kotter Say About Management and Leadership?

The clearest version of the distinction comes from John Kotter, a professor at Harvard Business School. In his 1990 Harvard Business Review article “What Leaders Really Do”, and his book A Force for Change: How Leadership Differs from Management published the same year, he argued that leadership and management are “two distinctive and complementary systems of action”.

In Kotter’s words, management is about coping with complexity and leadership is about coping with change. He broke each one into three tasks:

Management (coping with complexity)	Leadership (coping with change)
Planning and budgeting	Setting a direction
Organising and staffing	Aligning people
Controlling and problem solving	Motivating and inspiring

The pairs line up. Where a manager plans and budgets, a leader sets a direction for the plan to serve. Where a manager organises roles and fills them, a leader makes sure people understand the direction and pull the same way. Where a manager monitors results against the plan and fixes deviations, a leader keeps people moving when the going gets hard.

Kotter was also clear that neither is better. His concern was that many organisations were, in his phrase, over-managed and under-led: good at control, poor at adapting. The fix wasn’t to swap managers for leaders. It was to develop people who could do both. He was building on an earlier debate started by Abraham Zaleznik’s 1977 HBR article “Managers and Leaders: Are They Different?”, which saw the two as different types of person. Kotter’s more useful idea for a new manager is that they’re different types of work, and one person can learn both.

Why You Need Both

Picture two teams. In the first, the manager is warm, enthusiastic and full of ideas, but the rota is a mess, nobody knows who owns what, and deadlines slide. In the second, everything runs to the minute, but nothing ever improves and the best people leave because there’s nowhere to grow. The first team has leadership without management. The second has management without leadership.

You can be a manager without being a leader, and plenty of people are. You can also lead without being a manager: the experienced colleague everyone turns to, the person who suggests a better way and gets others to try it. What you can’t do, if you’re responsible for a team, is pick one and ignore the other for long.

A useful habit is to ask which one a situation needs. A recurring error in an invoice process is a management problem: fix the process, check it, move on. A team that has stopped bringing ideas to meetings is a leadership problem: no checklist will fix it. Getting that diagnosis right saves a lot of wasted effort.

How you lead and manage also varies with the person and the moment, which is where management styles come in. Our guide to management styles and when to use each covers the eight you’ll meet most often.

What Changes When You Step Up From Doer to Manager?

Most new managers are promoted because they were good at the job. That’s the trap. The skills that made you a strong technician, salesperson or nurse are not the skills that make you a good manager, and the habits that served you well can start to work against you.

Here’s what actually changes:

• Your results come through other people. Your own output used to be the measure. Now it’s the team’s output, and your job is to make that better, not to be the best performer on it.
• Your time stops being your own. Interruptions, questions and other people’s problems become a large part of the job. That isn’t a distraction from the work; it often is the work.
• Your relationships shift. If you’ve been promoted from within, yesterday’s peers now report to you. Friendly is fine. Being one of the gang, while also deciding who gets the overtime, is not.
• You see less of the detail. You can’t check everything and shouldn’t try. You have to trust, delegate and then check in, which feels uncomfortable at first.
• Your feedback carries more weight. An offhand comment from a colleague is forgettable. The same comment from the boss can keep someone awake at night.

Under pressure, new managers fall back on what they know: doing the technical work themselves. It feels productive, but it leaves the team without a manager. This is the transition our management training for new managers and team leaders is built around.

The First 90 Days as a New Manager

You don’t need a grand plan on day one. You need to understand the team, earn some trust, and fix the things that are obviously getting in people’s way. Michael Watkins’ book The First 90 Days (Harvard Business Review Press) is the best-known treatment of role transitions if you want to go deeper. Here’s a practical version for a first-time manager.

Days 1 to 30: Listen and Learn

1. Hold a first one-to-one with everyone in your first fortnight. Ask what’s going well, what gets in their way, and what they need from you. Mostly listen.
2. Agree expectations with your own manager. What does success look like at three months and at a year? What are you allowed to decide on your own?
3. Learn the numbers and the rhythms. Which measures matter, what reports exist, which meetings happen and why.
4. Don’t change much yet. Quick fixes that the team has asked for are fine. Restructuring before you understand the work is not.

Days 31 to 60: Set the Rhythm

1. Put regular one-to-ones in the diary and protect them. Fortnightly or monthly works for most teams.
2. Be clear about standards. Write down what good looks like for the main parts of the job, and talk it through with the team.
3. Start delegating properly. Pick one or two things you’re still holding on to and hand them over with clear authority and check-in dates.
4. Give your first pieces of specific feedback, both positive and corrective. The sooner feedback becomes normal, the easier it gets.

Days 61 to 90: Start to Lead

1. Share a simple direction for the team. Two or three priorities for the next six months, and why they matter.
2. Deal with anything you’ve been avoiding. A performance issue that’s still there at day 90 has become your issue, not your predecessor’s.
3. Ask for feedback on yourself. What should you keep doing, stop doing, start doing?
4. Review with your manager against the expectations you agreed in month one.

The checklist version of this is in the New Manager Toolkit at the end of this guide.

The Core Skills Every New Manager Needs

Leadership books talk about vision and inspiration. Day to day, management comes down to a handful of conversations done well and done often. These five are the ones that make the biggest difference.

One-to-One Meetings

A one-to-one is a regular, private conversation between you and each person who reports to you. It’s the single most useful habit a new manager can build, because nearly everything else (feedback, coaching, spotting problems early) happens inside it.

The biggest mistake is turning it into a status update. You can get a task list from a project tracker. Use the time for the things that don’t come up anywhere else: how the person is doing, what’s in their way, what they want to learn, and what they need from you. Let them own the agenda and keep your notes so you can follow up next time.

Delegation

Delegation is handing over a piece of work, with the authority to do it, to someone who can learn from it. It isn’t dumping the jobs you don’t like, and it isn’t handing something over and vanishing.

Good delegation makes three things clear: what the outcome is, how much authority the person has (from “look into it and recommend” through to “decide and just let me know”), and when you’ll check in. If you skip the authority part, people either come back to you for every decision or overstep without realising.

Feedback

Feedback is how people learn what to keep doing and what to change. New managers tend to give too little of it, then too much at once when something goes wrong.

A simple structure helps. The SBI model from the Center for Creative Leadership asks you to describe the Situation (when and where), the Behaviour (what you actually saw or heard, not your interpretation of it) and the Impact (what effect it had). “In Tuesday’s client call, you summarised the actions at the end before anyone asked. It meant the client left clear on next steps and we didn’t need a follow-up email.” Specific feedback like that is easier to give and much easier to act on.

Coaching

Coaching means helping someone work out the answer rather than giving it to them. It feels slower than telling, and in the moment it is. Over months it’s far quicker, because your team stops needing you for every decision.

You don’t need to be a trained coach to start. Swap one instruction a day for a question: “What have you tried?”, “What options can you see?”, “What would you do if I weren’t here?” Then let the person answer.

Managing Performance

Managing performance is setting clear expectations, noticing early when someone is falling short, and dealing with it fairly. Most performance problems that end up in formal processes started as small issues nobody mentioned.

Acas guidance on challenging conversations makes the same point: have a quiet word at the first sign of a problem, prepare by getting the facts straight, and hold the conversation face to face where you can. Check your organisation’s own policies before anything becomes formal, and involve HR early if it might.

Common Traps for New Managers

Almost every new manager falls into at least one of these. Knowing them in advance makes them easier to climb out of.

• Staying the best technician on the team. You jump in to fix things because it’s quicker. The team learns to wait for you, and you end up working late doing their work and none of yours.
• Trying to stay everyone’s friend. Being liked is pleasant. Being fair, consistent and clear is what people actually respect. You can be warm without avoiding hard calls.
• Avoiding the difficult conversation. The small issue you don’t raise in week two becomes the big issue in month six, and by then the person reasonably asks why nobody told them sooner.
• Changing everything at once. A new broom feels decisive, but changes made before you understand the work often undo things that were there for good reasons.
• Treating one-to-ones as optional. They’re the first thing to be cancelled when it gets busy, which is exactly when people need them most.
• Managing everyone the same way. An experienced, confident person needs room. Someone new to a task needs clearer direction. Treating them identically frustrates both.
• Not asking for help. New managers often feel they should already know how to do this. Nobody does. Ask your own manager, a mentor or a peer.

How to Build Management and Leadership Skills

You get better at managing people the same way you got better at your old job: practice, feedback and a bit of structure. Reading helps. Doing helps more.

1. Pick one skill at a time. Start with one-to-ones, then feedback, then delegation. Trying to improve everything at once improves nothing.
2. Practise in low-stakes moments. Give positive feedback using a structure before you need to give corrective feedback. Delegate a small task before a big one.
3. Get feedback on your management. Ask your team directly, or ask your own manager to sit in on a team meeting and tell you what they noticed.
4. Learn alongside other new managers. A cohort of first-time managers working through the same skills builds a shared language and a support network. The Acas guidance on performance management is a sound, free starting point on the basics.
5. Get one-to-one support for the harder parts. If you’re stepping into a bigger leadership role, or a specific situation keeps tripping you up, leadership coaching gives you a private space to work on your own style and challenges.

If you’re responsible for developing a group of managers rather than just yourself, start by finding out where the real gaps are. A training needs analysis stops you spending money on training people don’t need. The CIPD’s factsheet on line managers sets out how much of an organisation’s people management sits with them, which is why the investment matters.

What to Do This Week

You don’t need to master everything at once. This week, do three things:

1. Book a one-to-one with each person in your team if you haven’t already, using the template in the toolkit below.
2. Write down one thing you’re still doing that someone else should own, and plan how to hand it over using the delegation planner.
3. Give one piece of specific, positive feedback using Situation, Behaviour, Impact.

If you’d like your new managers to build these skills together, with practical sessions and follow-ups at 30, 60 and 90 days, take a look at our management training and tell us what your managers need.
