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...]
What is Resource Leveling?
Resource leveling is the smoothening of resource usage to increase project efficiency. It is performed to realize a trade off between project duration and project cost. Traditional project scheduling techniques do not take resource usage into account, and often produce erratic resource usage that drives up the project budget. For example, let's say you have a … [Read more...]
How to Draw a Network Diagram
In project management, the network diagram is a graphical depiction of a project schedule which uses boxes to represent each task. It is used to determine the critical path, as well as the float of each task. Critical Path: The tasks which define the completion date of the project. They cannot finish late, or be moved, or the overall project completion … [Read more...]
Types of Project Resources
A project manager that fails to allocate project resources is like a carpenter without a hammer. That's why estimating task resources is an integral step in project planning. It also happens to be one of the most fundamental aspects of project management, one of the steps that the project manager utilizes on a day to day basis. Types of Resources Each task on … [Read more...]
How to Draw a PERT Chart
The Program Evaluation and Review Technique (PERT) is an important step in project scheduling. 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 as arrows Milestone dates are nodes PERT charts are also called … [Read more...]
Project Management for Small Projects
Studies show that over 85% of projects have a value below $100,000. These are projects where the bulk of the work happens within only a few weeks to a month. Because of their short duration, these types of projects have their own unique set of circumstances that warrant a slight adaptation of project management methodologies. Googling project management search terms … [Read more...]
