The Program Evaluation and Review Technique (PERT) is an important step in project scheduling. A PERT chart is a tool used to plan the execution of tasks within a project. PERT charts are a central part of any project management course. They are quick to draw and intuitive to use. How to Draw a PERT Chart There are two rules: Tasks (activities) are represented … [Read more...]
ACWP (Earned Value Analysis)
The real benefit of the earned value method is in the early warning signal it provides. In my previous life at a large engineering company, I saw many project managers get to a monthly billing cycle before they realized the project was behind, and even then they would rationalize it by deciding their project team was going to be more efficient in the next cycle. Suffice … [Read more...]
Estimating the Project
In 1986, the NASA Space Shuttle Challenger exploded spectacularly upon take-off in front of one of the largest live TV audiences in history (to that time). The investigation concluded that several tiny O-rings that sealed the rocket booster to the fuel supply failed. These O-rings were about 1 foot in diameter. Just like the tiny O-rings were able to bring down the … [Read more...]
30 Example Project Resources
I once experienced a project horror story whereby a piece of equipment was snowed in at a previous project, delaying the project by several weeks until a transport vehicle could get to the stranded machine. Since there are relatively few of these around, the project either had to wait or additional costs had to be incurred to procure another one. Managing these types … [Read more...]
What Project Managers can Learn from Lean Six Sigma
Six Sigma was a powerful quality improvement system developed by Motorola that took the world by storm in the early 2000's with high profile adoptions by General Electric, Honeywell, and others. Lean was a manufacturing methodology originated by Toyota, which turned manufacturing on its head by focusing on minimizing idling products (inventory) rather than minimizing … [Read more...]
Planning a Project Schedule
If there's one part of project management that's bigger than all the rest, it's project scheduling. Since a project is defined as a temporary endeavor with a distinct beginning and end, defining when that end takes place and making sure it finishes on time are extremely important to any project, large or small. Professional project managers look at the schedule every … [Read more...]
Steps in Project Scheduling
Project scheduling is to a project manager like landing an airplane is to a pilot. It is often the largest and most visible aspect of project management. In this article, I will develop a professional, resource levelled project schedule that provides tremendous confidence in the ability to meet the project deadline. First, let's deal with the theoretical foundation. … [Read more...]
5 Steps to Develop a Bulletproof Project Schedule
Project scheduling is the key to ensuring the original project plan and final project outcome are at least close enough to call the project a success. It's the map that guides the ship. Good project managers look at the schedule constantly, sometimes on a daily basis, and take the actions necessary to stay on track. Because the definition of a project requires it to … [Read more...]
The Critical Chain Method Explained
The Critical Chain Method is a relatively new concept in project management. It was developed and popularized by Dr. Elihayu M. Goldratt in his book Critical Chain (1997), which is written as a novel but outlines the methods used to ensure that projects complete on time. Critical Chain vs. Critical Path The Critical Chain method is similar to the Critical Path Method … [Read more...]
A Critical Path Method Example
When you, the project manager, need to make sure a project finishes on time, there is a science as well as an art form involved. But the science tends to enhance the art, in other words, if you know the science you will be that much better at practicing the art form. In yesterday's post we outlined the critical path method which is the professional project manager's … [Read more...]
