Across this website, we use the following definition of the term "project":
A project is any endeavor which is unique in
In sub-section "What Is a Project?", we go a little bit deeper into details of this definition and give an example.
We call the combination of scope, schedule and budget the triple constraint of project management because we cannot change one of the three cornerstones without changing the other two.
Definition of project management: Project management is the management of the triple constraint to the satisfaction of the stakeholders of the project. We consider project management being a process which we describe more detailed in PM Process.
Let's take an example, a typical construction project. We have a customer who wants to create a certain building and a supplier who will construct that building. Now, we can list the natural flow of major project activities as follows, divided into customer activities and supplier activities.
This we call the project life cycle or project management life cycle. By including the major milestones for both parties, and following the view of the customer, we recognize the four project life cycle phases.
We go through more detailed descriptions of these four phases on separate pages:
In this section, fundamentals of project management, we would like to emphasize some aspects of the project cost. During the first two phases, we create the so called accumulative project cost plan. It could look like this:
Under ideal conditions we would expect the real accumulated project cost being virtually the same as planned in definition and planning phase. In an ideal world, we would be able to implement the project plan without changes or additional work being necessary. But the reality of project implementation is different in our world. We are not able to plan for each and every eventuality, sometimes things go wrong we never could think of, let alone plan for. Additionally, our resources for project planning are usually limited, so that we more or less consciously remain a little rough and vague with parts of our project plan until signing any contract.
The real accumulated cost typically looks like the following graphical representation of the fundamentals of project management:
This appears to be a general project management principle or one of the fundamentals of project management:
We tend to spend less in definition and planning phase but have to pay a multiple of those savings in implementation and closure phase, and thus cannot stay within the planned schedule and budget.
What are the reasons for this phenomenon?
Having managed many projects, from small to medium, to large, to very large, we can see reasons in the following areas:
If you are looking for a complete description of the core project planning process, we offer you our e-book, Project Planning Guide, in PDF-format. It covers the 10 steps of planning and contains an example (a photo-voltaic solar plant) to illustrate the application of the explained principles.Click here for more info, or
On this web site we propose kind of a master plan that helps to minimize extra work and additional cost in implementation and closure phase, and thus, to improve your project results. In sub-section Project Management Basics, we present pre-requisites for this whole web site.
In case you would like to use practical and useful packages of tools, templates and checklists, here you can get them. They save you a lot of time, are easy to use and easy to change:
