Cost
The work content identified by WBS is used to estimate the approximate
cost required. The estimated cost is used as the basis to define and manage
the budget. An “EVMS (Earned Value Management System)” is used for
cost management.
●Earned value management system
An “EVMS (Earned Value Management System)” is a technique for
quantitatively evaluating the progress of a project by comparing it with the
budget and work schedule.
EVMS is used to prepare a cost plan based on the estimated person-hours
derived from the breakdown of work from the WBS, and the variance of
the schedule and cost is measured. The measured results are then analyzed
to forecast work delays and over-budgeting, and adjustments are made to
the schedule and budget.

Person-hours
“Person-hours” represent the volume of
work required for activities such as system development. Person-hours are
typically indicated in person-month
units.
Reference
Person-months
“Person-months” are a unit of personhours. One person-month equals the
amount of work performed by one person in a single month.
Example Work that takes one person
three months to accomplish represents
three person-months of work.
Example Work that takes two persons
three months to accomplish represents
six person-months of work.
Project management
Project members are procured based on the deliverables identified by
WBS, as well as work scope, time, cost, and quality. The project team is
also structured and trained according to the deliverables and work scope.
The success of the project hinges on manpower and teamwork. In order to
effectively capitalize on the capabilities of all persons involved in the
project, it is necessary to prepare an optimum environment and assign the
right project members to the right positions.

Chapter 5
Quality is maintained and improved by defining and managing the desired
quality targets of the deliverables, which are based on the deliverables
identified by WBS. The following items are reviewed and summarized in a
“quality management plan:” targets, quality maintenance and improvement plan, quality inspection technique, review plan, and testing method.
Reference
Communication
It is necessary to manage communication so that there is sharing of information, and mutual understanding between working project members and
the project manager. E-mail is typically used for communication, but other
methods are also used to share information within the project such as preparing mailing lists and using groupware. In addition, regular meetings are
held to encourage mutual understanding between project members, information sharing, and reporting on progress.
