Ever feel like you’re doing everything right at work - ticking all the boxes, meeting your deadlines, even getting praise from your boss - but you’re still stuck in the same role? You see others getting ahead, and you can’t quite figure out what they’re doing differently. If your results are high but your title hasn't changed, you likely need a new strategy for [how to get promoted faster](/blog/career-advancement-tips "Practical career advancement tips to help you move forward").
The truth is, simply doing your job well isn’t always enough. To really accelerate your career, you need to be strategic. You need to show that you’re ready for the next level. But what does that actually mean in practice? It doesn’t mean working 80-hour weeks or burning yourself out. You need to prioritize work that your manager and their peers actually notice. This is where the 15 percent rule comes in - a simple but powerful framework for taking on more responsibility, gaining visibility, and setting yourself up for that next promotion.
What is the 15 percent rule?
The 15 percent rule is straightforward: dedicate 15 percent of your work time to tasks and projects that fall outside your core job description. If you work a 40-hour week, that’s about six hours. This isn’t about slacking off on your main duties. In fact, you need to be excelling in your current role for this to work. It’s about using a portion of your time for high-impact, high-visibility work that aligns with the company’s goals and your own career aspirations. Think of it as an investment in your future. The other 85 percent of your time is for doing your job - keeping the lights on. The 15 percent is for showing your potential to do more.
Why it works
There are a few reasons why the 15 percent rule is so effective. First, it pushes you out of your comfort zone. When you’re constantly learning and taking on new challenges, you grow. You develop new skills and gain a broader understanding of the business. Second, it gets you noticed. When you’re involved in projects that are important to the company’s leadership, you become more visible. People start to see you as a problem-solver and a go-getter. This is a key part of [how to get promoted faster](/blog/career-advancement-tips "Practical career advancement tips to help you move forward"). Handling higher-level tasks now provides the proof your manager needs to justify your pay raise or title change later. You can get a feel for the responsibilities and expectations of the next level, which can help you decide if it’s the right move for you.
How to find your 15 percent
So, how do you identify the right 15 percent projects? It’s not about just raising your hand for everything. It’s about being strategic. Here’s what to look for:
- **Listen to what leadership is talking about.** What are the big goals for the company this quarter or this year? What are the challenges they’re facing? These are clues to what’s important. If you can contribute to solving a major company problem, you’ll be seen as incredibly valuable.
- **Look for recurring problems.** Are there any issues that keep coming up in your team or department? Is there a process that’s inefficient or a system that’s not working as well as it could? If you can find a way to fix a persistent problem, you’ll be a hero.
- **Think about your own career goals.** Where do you want to be in a year or two? What skills do you need to develop to get there? Look for projects that will help you build those skills and gain experience in the areas you want to grow into.
How to get your manager on board
You can’t just start spending 15 percent of your time on new projects without talking to your manager. Before meeting, list exactly how your side project solves a current team pain point. Here’s how to approach it:
- **Do your homework.** Before you talk to your manager, have a clear idea of what you want to work on and why. Be prepared to explain how it will benefit the company and how you’ll manage your time to ensure your core responsibilities don’t suffer.
- **Frame it as a win-win.** This isn’t about you doing less of your job. It’s about you adding more value. Explain to your manager that you’re committed to excelling in your current role and that you want to take on more responsibility to help the team and the company achieve its goals.
- **Start small.** You don’t have to jump into a huge project right away. Suggest starting with a smaller task or a pilot project to prove that you can handle the extra workload. Once you’ve shown that you can deliver, it will be easier to get approval for bigger projects in the future.
The art of saying no
As you start to become more visible and take on more responsibility, you’ll likely be asked to get involved in more and more things. This is where the [art of saying no becomes crucial](/blog/work-life-balance-advice "Practical work-life balance advice for overwhelmed professionals"). You can’t do everything, and if you try, you’ll burn out. Be selective about what you say yes to. Ask yourself if the project aligns with your career goals and if it’s a good use of your 15 percent time. If it’s not, it’s okay to politely decline.
Don’t let your day job suffer
This is the golden rule of the 15 percent rule. It only works if you’re already excelling in your current role. If your performance starts to slip, you’ll lose the trust of your manager and your colleagues. Make sure you’re staying on top of your core responsibilities and that you’re not letting your 15 percent projects interfere with your day job. This might mean being more organised with your time or finding ways to work more efficiently. Moving up requires shifting your focus from completing assigned tickets to solving higher-level business problems.
What it looks like in practice
Let’s look at a couple of examples of how the 15 percent rule can work in different roles:
- **The Software Engineer:** A software engineer might spend their 15 percent time developing a new tool to automate a tedious manual process for their team. This not only saves the team time and effort but also showcases the engineer’s initiative and problem-solving skills.
- **The Marketing Manager:** A marketing manager could use their 15 percent time to research and develop a proposal for a new social media channel that the company isn’t currently using. This demonstrates strategic thinking and a forward-looking approach.
What to do next
Ready to put the 15 percent rule into action? Here’s what to do next:
- **Start by excelling in your current role.** Before you do anything else, make sure you’re exceeding expectations in your day job.
- **Identify your 15 percent.** Start looking for high-impact, high-visibility projects that align with your career goals and the company’s priorities.
- **Talk to your manager.** Schedule a meeting to discuss your proposal and get their buy-in.
- **Start small and deliver.** Choose a manageable first project and knock it out of the park.
