1995 CHAOS study cited user involvement, a clear
project mission, a clear statement of requirements, and proper planning as
being important for project success |
|
The program manager of Keller Graduate School of
Management cites proper project definition and scope as the main reasons
projects fail |
|
|
|
|
Scope refers to all the work involved in
creating the products of the project and the processes used to create them |
|
Project scope management includes the processes
involved in defining and controlling what is or is not included in the
project |
|
The project team and stakeholders must have the
same understanding of what products will be produces as a result of a
project and what processes will be used in producing them |
|
|
|
|
Initiation: beginning a project or continuing to
the next phase |
|
Scope planning: developing documents to provide
the basis for future project decisions |
|
Scope definition: subdividing the major project
deliverables into smaller, more manageable components |
|
Scope verification: formalizing acceptance of
the project scope |
|
Scope change control: controlling changes to
project scope |
|
|
|
|
|
|
|
|
The first step in initiating projects is to look
at the big picture or strategic plan of an organization |
|
Strategic planning involves determining
long-term business objectives |
|
IT projects should support strategic and
financial business objectives |
|
|
|
|
|
|
Many organizations follow a planning process for
selecting IT projects |
|
First develop an IT strategic plan based on the
organization’s overall strategic plan |
|
Then perform a business area analysis |
|
Then define potential projects |
|
Then select IT projects and assign resources |
|
|
|
|
|
|
|
There are usually more projects than available
time and resources to implement them |
|
It is important to follow a logical process for
selecting IT projects to work on |
|
Methods include focusing on broad needs,
categorizing projects, financial methods, and weighted scoring models |
|
|
|
|
|
|
|
|
|
It is often difficult to provide strong
justification for many IT projects, but everyone agrees they have a high
value |
|
“It is better to measure gold roughly than to
count pennies precisely” |
|
Three important criteria for projects: |
|
There is a need for the project |
|
There are funds available |
|
There’s a strong will to make the project
succeed |
|
|
|
|
|
One categorization is whether the project
addresses |
|
a
problem |
|
an opportunity, or |
|
a directive |
|
Another categorization is how long it will take
to do and when it is needed |
|
Another is the overall priority of the project |
|
|
|
|
|
|
|
Financial considerations are often an important
consideration in selecting projects |
|
Three primary methods for determining the
projected financial value of projects: |
|
Net present value (NPV) analysis |
|
Return on investment (ROI) |
|
Payback analysis |
|
|
|
|
|
|
Net present value (NPV) analysis is a method of
calculating the expected net monetary gain or loss from a project by
discounting all expected future cash inflows and outflows to the present
point in time |
|
Projects with a positive NPV should be
considered if financial value is a key criterion |
|
The higher the NPV, the better |
|
|
|
|
|
|
|
Return on investment (ROI) is income divided by
investment |
|
ROI =
(total discounted benefits - total discounted costs) / discounted costs |
|
The higher the ROI, the better |
|
Many organizations have a required rate of
return or minimum acceptable rate of return on investment for projects |
|
|
|
|
|
|
Another important financial consideration is
payback analysis |
|
The payback period is the amount of time it will
take to recoup, in the form of net cash inflows, the net dollars invested
in a project |
|
Payback occurs when the cumulative discounted
benefits and costs are greater than zero |
|
Many organizations want IT projects to have a
fairly short payback period |
|
|
|
|
|
|
|
|
|
A weighted scoring model is a tool that provides
a systematic process for selecting projects based on many criteria |
|
First identify criteria important to the project
selection process |
|
Then assign weights (percentages) to each
criterion so they add up to 100% |
|
Then assign scores to each criterion for each
project |
|
Multiply the scores by the weights and get the
total weighted scores |
|
The higher the weighted score, the better |
|
See “What Went Right?” for a description of how
a mortgage finance agency uses a weighted scoring model for IT projects |
|
|
|
|
|
|
After deciding what project to work on, it is
important to formalize projects |
|
A project charter is a document that formally
recognizes the existence of a project and provides direction on the
project’s objectives and management |
|
Key project stakeholders should sign a project
charter to acknowledge agreement on the need and intent of the project |
|
|
|
|
|
|
|
|
|
A scope statement is a document used to develop
and confirm a common understanding of the project scope. It should include |
|
a project justification |
|
a brief description of the project’s products |
|
a summary of all project deliverables |
|
a statement of what determines project success |
|
|
|
|
|
After completing scope planning, the next step
is to further define the work by breaking it into manageable pieces |
|
Good scope definition |
|
helps improve the accuracy of time, cost, and
resource estimates |
|
defines a baseline for performance measurement
and project control |
|
aids in communicating clear work
responsibilities |
|
|
|
|
A work breakdown structure (WBS) is an
outcome-oriented analysis of the work involved in a project that defines
the total scope of the project |
|
It is a foundation document in project
management because it provides the basis for planning and managing project
schedules, costs, and changes |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Using guidelines: Some organizations, like the
DOD, provide guidelines for preparing WBSs |
|
The analogy approach: It often helps to review
WBSs of similar projects |
|
The top-down approach: Start with the largest
items of the project and keep breaking them down |
|
The bottoms-up approach: Start with the detailed
tasks and roll them up |
|
|
|
|
|
|
1. A unit of work should appear at only one
place in the WBS. |
|
2. The work content of a WBS item is the sum of
the WBS items below it. |
|
3. A WBS item is the responsibility of only one
individual, even though many people may be working on it. |
|
4. The WBS must be consistent with the way in
which work is actually going to be performed; it should serve the project
team first and other purposes only if practical. |
|
5. Project team members should be involved in
developing the WBS to ensure consistency and buy-in. |
|
6. Each WBS item must be documented to ensure
accurate understanding of the scope of work included and not included in
that item. |
|
7. The WBS must be a flexible tool to
accommodate inevitable changes while properly maintaining control of the
work content in the project according to the scope statement. |
|
|
|
|
|
It is very difficult to create a good scope
statement and WBS for a project |
|
It is even more difficult to verify project
scope and minimize scope changes |
|
Many IT projects suffer from scope creep and
poor scope verification |
|
FoxMeyer Drug filed for bankruptcy after scope
creep on a robotic warehouse |
|
Engineers at Grumman called a system “Naziware”
and refused to use it |
|
|
|
|
|
|
Insist that all projects have a sponsor from the
user organization |
|
Have users on the project team |
|
Have regular meetings |
|
Deliver something to project users and sponsor
on a regular basis |
|
Co-locate users with the developers |
|
|
|
|
Develop and follow a requirements management
process |
|
Employ techniques such as prototyping, use case
modeling, and Joint Application Design to thoroughly understand user
requirements |
|
Put all requirements in writing and current |
|
Create a requirements management database |
|
Provide adequate testing |
|
Use a process for reviewing requested changes
from a systems perspective |
|
Emphasize completion dates |
|
