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...]
A Project Health Check
When a patient is first wheeled into the emergency room, the first priority of any doctor is their vital signs, that is, pulse, breathing, body temperature, and blood pressure. Regardless of the injury, if the vital signs are not stable the patient is dying and all efforts must be directed toward stabilizing them prior to treating the original injury. Project management … [Read more...]
How to Perform a Critical Path Analysis
Critical path analysis is a method used in project management for optimizing the completion of project tasks. If you need to go to yoga class and buy groceries, but yoga class doesn't start for 2 hours, you should buy the groceries first. The critical path is defined as the list of tasks which determine the completion date of the project. If you need an extra day … [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...]
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...]
Estimating Activity Durations
Like the tiny O-rings that brought down the space shuttle Challenger, one small underestimation often results in a chain reaction that the project can't recover from. Therefore, project planning needs to make sure that enough time is assigned to each task. Once the project has been divided into activities and resources assigned to those activities, the next step is to … [Read more...]
Types of Task Dependencies
In project management, all tasks have dependencies. If they didn't they wouldn't be part of the project. That is, a task that doesn't need to be completed in order to finish the project is not part of the project. It's an orphan adrift at sea. There are four types of task dependencies, and each one has its own specific reason why you would use it. … [Read more...]
