Perform Cost
Estimation
Cost estimation is often difficult in standard projects. It
is more complex and difficult in international projects. One problem is that
there is often no way to link the actual costs in the project to the project
plan. Another problem is that budget estimation is performed individually based
on the single project leader.
The overall project management approach in this chapter provides
for an improvement in this situation.
-
There are two project leaders involved so that there is a
wider perspective of what is to be estimated.
-
There are project templates for each type of project. As
time goes on and experience grows, the template can grow in size. Lower-level
tasks can be added.
-
Estimated durations can be given for some tasks that are
performed in the plans that follow a specific template.
-
Issues are associated with tasks in the templates.
-
Budgeted and actual costs for projects can be inserted in
fields in the project plan, thereby facilitating analysis.
-
By type of project, the costs (budgeted and actual) can be
associated with tasks in the project templates.
Cost estimation is improved since the costs can be linked to the
template.
The method is then to associate a new project with a template.
Then the project leaders review the template to refine the tasks. They can
review the issues associated with the tasks in the template and make
adjustments. The project leaders can now perform improved estimation using this
additional information.
There is an additional benefit of this approach. When
management poses questions, asks for budget cuts or budget increases to reduce
schedules, the project leaders can use a copy of the template file to perform
“what if” analysis. This is more credible to management since it is based on
more concrete data than just raw experience of one person.
