[New Manager] What is a Gantt chart?

 As a new project manager, understanding Gantt charts is essential for effective project planning and management. Let’s dive into what Gantt charts are, how they look, how to identify key elements, common mistakes to avoid, and some useful references.

What Is a Gantt Chart?

A Gantt chart is a powerful project management tool that visually represents project activities over time. It provides a clear timeline, allowing project professionals to monitor progress, allocate resources, and manage dependencies. Here’s a concise definition:

Gantt Chart: A graphical representation of activity against time, showing tasks, start and end dates, dependencies, and task ownership.

Project milestone: a key event or action that signifies a significant stage of progress. It can denote the start or finish of a project, completion of a major task, or any other noteworthy achievement. Milestones help track project progress and ensure alignment with project goals.

Anatomy of a Gantt Chart

  1. Timeline: The top of the chart displays the project’s time frame.
  2. Task Bars (Gantt Bars): Each task/activity corresponds to a colored bar. The position and length of the bar represent the task’s start and end dates.
  3. Dependencies: Arrows connecting bars indicate task dependencies (e.g., Task B depends on Task A).
  4. Task Ownership: The responsible person/team for each task is specified.
  5. Deadlines: Milestones or project deadlines are marked.

How to Create a Gantt Chart

  1. Task Identification: List all project tasks and estimate their durations.
  2. Dependencies: Determine which tasks are dependent on others.
  3. Timeline: Arrange tasks in chronological order.
  4. Resource Allocation: Assign team members to tasks.
  5. Bar Creation: Draw bars for each task based on start and end dates.
  6. Critical Path: Identify the longest path from start to completion (critical tasks).

Common Mistakes to Avoid

  1. Overloading the Chart: Keep it concise; too many tasks clutter the view.
  2. Ignoring Dependencies: Accurate task sequencing is crucial.
  3. Neglecting Updates: Regularly update the chart as progress occurs.
  4. Lack of Clarity: Ensure task descriptions are clear and concise.
  5. Not Using Software: Manual charts can be error-prone; use project management tools.

Getting PMP certified

I've got a lot of friends asking me about how to get certified. Each time, I had to remember how many hours of experience one had to have, and how many hours of learning, and then which where the links that were most useful for me, as well as all the books and software I have ever used. In terms of specific requirements for getting certified, the best resource will always be pmi.org, with a direct link to the requirements: PMI site - Obtaining the Credential . The site lists a credential overview, and then there (currently) 5 handbooks for the 5 available certifications. There is also a page with how to prepare for the exam, from an administrative point of view. If you are new to project management, then you will have to go with the CAPM certification. Then, the rest of certifications are for more and more experienced PMs. I only know well about the PMP certification, as it's the one I've got. First step is to ensure that you meet the elgibility requirements. At the t...

What a day...

How many times did it happen to you to get home, and think about your day, and suddenly remembering that you did not all the things on your (mental) list?... It just happened to me, and I am angry with me... Is it something common? What do you do when this happens to you? How do you organize your time?

PMP certification - prep questions

As the Getting PMP certified article got so much positive feedback, I though I should also share some of the providers of free tests. I have also used them during my certification prep period as well, and I've found them really useful. You should simulate your exam at least 3 times before stating that you are ready for the BIG TEST, so the links below should help you a lot. Still, one word of caution: not all the questions seem to have the right response, and not all explanations are really in line with PMBoK - but if you have a good knowledge of the practice part of Project Management, and if you've read the books I've recommended, you can already discover them. Don't go for the real PMP exam if you don't score 80% in these simulations - they seemed to me a little bit easier than the real exam. http://www.pmhub.net/ PMSuccess offers via PMHub.net 400 questions to play with. Not an exam simulation per-se, but you can always try to do 200 questions in a row t...
