Outline Materi
• IT Project Management

• Issue on complex IT project
4
IT PROJECT MANAGEMENT
• IT Project management requires knowledge of system development methodologies:
– SDLC– Prototyping– RAD– Purchasing life cycle
5
IT PROJECT MANAGEMENT• Project Management Institute (PMI)
– International society of project workers– Certified thousands of professionals since 1984– PM competencies certified by PMI include eight
areas:
6
IT PROJECT MANAGEMENT
• Most projects share common characteristics:
1. Risk and uncertainty highest at project start
2. Ability of stakeholders to influence project greatest at project start
3. Cost and staffing levels lower at project start and higher toward end
(PMI, 1996)
7
IT PROJECT MANAGEMENT
Project:• Temporary endeavor to create unique product or service• Typically is a one-time initiative• Can be divided into multiple tasks• Requires coordination and control• Has a definite beginning and end

IT PROJECT MANAGEMENT
Project:• Temporary endeavor to create unique product or service• Typically is a one-time initiative• Can be divided into multiple tasks• Requires coordination and control• Has a definite beginning and end
Program – a group of projects managed in a coordinated way to obtain benefits not available from managing them individually (PMI, 1996)
9
IT PORTFOLIO MANAGEMENT
IT Portfolio – set of IT project initiatives currently in progress, as well as requests for IT projects that have not yet been funded
10
IT PORTFOLIO MANAGEMENT
• Project categories to help with prioritization:
– Absolute must A mandate due to security, legal, regulatory, or end-of-life-cycle IT issues
– Highly Desired/Business-Critical Includes short-term projects with good financial returns
– Wanted Valuable, but with longer time periods for ROI (more than 12 months)
– Nice to Have Projects with good returns, but with lower potential business value
(Denis, et al., 2004)
11
PROJECT INITIATION
• Project charter• Scope statement• Feasibility analyses
– Economic– Operational– Technical
12
PROJECT INITIATION
• Economic feasibility– Formal cost-benefit analysis usually conducted– ROI calculated when benefits can be easily measured– Alternatives to ROI:
13
PROJECT INITIATION
Project Manager Characteristics
• Project manager can be:– IS manager– Business manager– Both
15
PROJECT INITIATION
Project Sponsor and Champion Roles
Sponsor:
• Participates in the development of the initial project proposal and the feasibility studies • May personally argue for project approval• Is usually the business manager who financially “owns” the project
16
PROJECT INITIATION
Project Sponsor and Champion Roles
Champion – a business manager who:
• Has high credibility as organizational spokesperson among user community• Is successful communicator of vision and benefits throughout the project
18
PROJECT PLANNING
Scheduling
• Work breakdown analysis:– Identifies phases and task sequence to
meet project goals– Estimates time of completion for each task– Results in a project master schedule that
identifies date and deliverable milestones
19
PROJECT PLANNING
Scheduling
Timeboxing – organizational practice in which a system module is to be delivered to user within a set time limit, such as 6 months
Work breakdown – a basic management technique that systematically subdivides blocks of work down to the level of detail at which the project will be controlled
20
PROJECT PLANNING
Budgeting
Two traditional approaches to estimating costs:
• Bottom-up– Cost elements are estimated for lowest level of work tasks and
then aggregated to give total project cost estimate
• Top-down (parametric cost estimating)
– Provides cost estimates for major budget categories based on historical experience
21
PROJECT PLANNING
Budgeting
• Inexperienced estimators may:
1. Be too optimistic about what is needed to do the job
2. Tend to leave out components
3. Not use a consistent methodology, and have difficulty recreating their rationales
22
PROJECT PLANNING
Staffing
Project staffing involves:
1. Identifying IT specialist skill mix needed
2. Selecting personnel who collectively have necessary skills and assigning them to work
3. Preparing personnel for specific team member work
4. Providing incentives to achieve project goals
23
PROJECT PLANNING
Staffing
(Based on productivity study by Hughes Aircraft Company in Roman, 1986)
Counterproductive Characteristics
24
PROJECT PLANNING
Planning Documents
Two typical planning documents:• Statement of Work (SOW)
– For the customer– High-level document that describes what project delivers and when– Contract between project manager and executive sponsor
• Project Plan– Used by project manager to guide, monitor, and control execution of project– Reviewed by managers or committees that oversee project
26
PROJECT PLANNING
Planning Documents
• PERT (or CPM)– Graphically models sequence of project tasks and
interrelationships using a flowchart diagram– Depicts a critical path – sequence of activities that will take
longest time to complete– Helps managers estimate effects of task slippage– If used, less likely to have cost and schedule overruns
27
PROJECT PLANNING
Planning Documents (PERT chart example)
(Reprinted from Valacich, George, and Hoffer, Essentials of Systems Analysis & Design, Prentice Hall, 2001)
28
PROJECT PLANNING
Planning Documents
• Gantt– Graphically depicts estimated times (and later actual times)
for each project task against a horizontal time scale
– Tasks presented in logical order along with bar graph showing estimated time duration for each task on a calendar
– Useful for displaying a project schedule and tracking progress of a set of tasks against project plan

PROJECT EXECUTION AND CONTROL
• Project plan needs to be refined and reassessed throughout life of project
• Software project management tools commonly used to help initiate and monitor project tasks
• Communication among project team members critical for task coordination and integration
• Communication throughout project to all stakeholders is key to project success
32
PROJECT EXECUTION AND CONTROL
Managing Project Risks
• PM Goal:– Manage risk of failing to achieve project objectives
• Causes of Risk:– Human error
– Project scope changes
– Unanticipated technology changes
– Internal politics
33
PROJECT EXECUTION AND CONTROL
Managing Project Risks
Ten IT-Related Risks and Potential Consequences
(Bashein, Markus, and Finley, 1997)
36
PROJECT EXECUTION AND CONTROL
Managing Business Change
• Change management:– Ability to successfully introduce change to individuals and
organizational units – Key to project success– Often involves change to power structures that must be recognized– Can be facilitated by using change models, such as Lewin/Schein
change model
37
PROJECT EXECUTION AND CONTROL
Managing Business Change
Three Stages of Lewin/Schein Change Model
Lewin/Schein Change Model
38
PROJECT CLOSING
• IT project deliverables completed• Formal user acceptance obtained or failed project terminated• Common questions for team members:
– What went right on this project?
– What went wrong on this project?
– What would you do differently on the next project, based on your experience with this project?
39
SPECIAL ISSUE: MANAGING COMPLEX IT PROJECTS
• Three factors critical to success of large, complex IT projects:
– The business vision an integral part of project
– A testing approach used at program level (not just individual application level)
– Used a phased-release approach (rather than single rollout strategy)
40
SPECIAL ISSUE: POST-MERGER IT INTEGRATION PROJECTS
• What makes for a successful merger?– Well-honed IT project management skills, and a program
management structure– Retaining IT talent needed for post merger IT integration
efforts– Quickly offering attractive retention contracts to key
personnel
