8 mistakes that will ruin any project

Project management stems from a solid foundation of good old-fashioned planning, time management, and organization, but a lot can go wrong along the way. A study of 10,640 projects from 200 companies across various industries found that only 2.5% of companies successfully completed 100% of their projects.

So why do so many projects fail? Many project managers fall into the same traps that hinder their success. Here are some pitfalls to be aware of when managing client projects.

1) You don’t fully define each team member’s responsibilities from the start

By the end of your first project meeting, every team member should have a clear understanding of the following two things:

Exactly what they need to contribute to the project as an individual.
How their individual contribution impacts the overall project goals.

As a project manager, the last thing you want to hear from a team member after a kickoff meeting is, “I don’t know where to start.” Each person needs to know what will be expected of them and exactly how their individual work will contribute to completing project milestones. By constantly emphasizing how meaningful and important each contribution is to success, project managers can keep team members fully engaged and productive.

2) You get bogged down in the details and lose sight of the big picture

When you find yourself stuck on a task and it seems to be wasting a lot of time, ask yourself a few questions:

Does this task align with the main project goals?
Can I clearly explain the greater purpose of this task to my team?

If the answer to either of these questions is “no,” then it’s time to take a step back and re-evaluate whether the work you’re doing aligns with the overall project goals. Every component of the project must align with a measurable end result. If you don’t know the clear reason behind a specific task, it’s not worth your valuable time and resources. You need to figure out why (or if) the task is important by checking with your team or abandoning it to move on to more productive work.

3) You choose the wrong project manager

The project manager role description often tends to be vague and scattered with buzzwords—”must be a team player,” “must be results-oriented,” “must have a proven track record.” But how exactly does this long and tedious list of basic skills align with what your team is actually trying to accomplish?

Project management is not a one-size-fits-all role—someone who was a successful project manager on a previous project is not necessarily the absolute right fit for another. Teams should sit down during the initial planning phase and write down a list of skills and attributes they think would be a good fit for the unique project at hand. This will help you identify a manager who can understand your challenges, strengths, and goals.

4) You don’t break the project down into manageable components

If someone asked you to bake a complex 15-tier cake without a recipe, you would have some trouble getting started and managing your progress. To succeed, you need someone to give you a cookbook that outlines each part of the process—otherwise, things will get messy.

The same goes for successful project management. If you only look at the final outcome of a project, it’s easy to get overwhelmed and start to falter. A good project manager needs to present the project in steps and checkpoints to ensure team members stay on track. Achievable, realistic milestones will help segment a daunting task into manageable parts that can be tackled daily. Including all these steps as they are approved by the client in a project management tool makes it easy to collaborate and stay updated on progress.

5) You don’t establish a clear communication framework

Planning a monthly meeting to discuss a project’s progress is great, but what happens between those calendar invites? Your team needs a way to share information and keep everyone updated on their work; otherwise, you risk members going off track and losing sight of important milestones.

To keep everyone on the same page, develop a well-defined communication system at the time of your kickoff meeting. Consider creating a shared calendar just for project deadlines or a shared document where team members can post updates. If at any point during a project you’re unsure of what your team members are working on, it’s time to check in. Over-sharing is better than under-sharing.
