Project Management

Outline

• Why review information needs and system requirements?

• What are three popular activities that can assist with project management?

Why review information needs and system requirements?

• Scope of the system – What are four elements for scoping a project?

• Critical success factors – What is important?

Scope Statement • Scope statement consists of two parts containing four

core elements; each element builds from previous Information Need 1) Goals

– What your project is going to accomplish? 2) Objectives or need-to-know questions

– How is your project accomplishing that goal? 3) Deliverables or information products

– Specific items or services that must be produced in order to fulfill the goals of the project produced in completion of an objective

Systems Requirements 4) Resources

– Identify the GIS resources (data, software, hardware, people) used to produce the deliverables

Critical success factors • Understanding of and consensus on project

goals/objectives by key stakeholders • Well-defined requirements derived from goals

and deliverables • Involvement from the stakeholders

– Communication plan • Well-defined project plan

– Project schedule, risk management plan • The use of established project management

practices

What are three popular activities that can assist with project management?

Applying project management activities to project implementation plan:

• Assigning roles and responsibility to personnel

- Work Breakdown Structure content used to develop Responsibility Assignment Matrix

• Understanding dependencies between tasks

- Program Evaluation and Review Technique

• Estimating the duration of project activities

- Critical Path Method

Work breakdown structure (WBS)

• Graphically display the deliverables of the project in a hierarchical fashion, i.e. levels of detail

• Organizes the work of the project into logical groupings

• Helps assign resources and estimate time and costs

Organizing the WBS levels • Level 1: the name of the project

– e.g. annual conference project • Level 2: deliverables or major milestones of the

project or project phases – e.g. PCs set up

• Level 3: tasks or grouping of tasks – e.g. Obtain PCs, Set up PCs

• … • Lowest level: work packages

– e.g. Arrange delivery, Load software

Organizing the WBS levels - tree form -

From Heldman 2005 Project management jumpstart

Organizing the WBS levels - outline form -

Task list

• Deliverable is a “noun” while task is “verb” action • Tasks are single activities, or units of related

work, completed to satisfy a project deliverable or the requirement of a deliverable

Organizing the WBS levels • Where to stop?

– Keep adding levels of the WBS until you’ve broken the work out to the point where responsibility for each unit of work can be assigned to a specific person or to a team

– work packages: the lowest level of a WBS where resource assignments and time/cost estimates are established

• Why identification codes? – allows you to uniquely identify each element of the WBS – serves as convenient reference numbers to other planning

information • Link to scope statement?

– Make sure all deliverables in scope statement are included in WBS

Constructing the Responsibility Assignment Matrix (RAM)

• Similar to personnel requirement in Stage 2 report • Assign roles and responsibilities to available resources

(staff)

• Row: types of resources needed • Column: WBS work packages • For resource assignments, use expert judgment and

historical information

Estimating activity durations

• Similar to timing requirements of Stage 2 • Determine the number of work periods

needed to complete the tasks defined in the WBS

• Use Gantt chart to identify the duration of tasks

• Use Gant chart to identify when tasks are likely (roughly) to occur

Program Evaluation & Review Technique (PERT) uses a network diagram

• Tasks are dependent on one another, thus one task cannot start or finish until the previous task has finished or started

• Network diagram shows the tasks of the project in sequential order

• Visualizes the progress of the project, and determines how the work of the project must be performed

• Critical path: longest (duration) full path on the project

PERT

Each box is a project task. Arrows show dependencies between tasks. The tasks in red are on the critical path. If any tasks on the critical path take longer than planned, the whole project will slip unless something is done.

Critical path method (CPM)

• Used to calculate the duration of the project • Critical path is the longest full path on the project;

when you change the duration of a critical path task, it always changes the project duration

• Float time: the amount of time you can delay the early start of a task without delaying the finish date of the project

• All tasks with zero float time are considered critical path tasks

Critical path method

1. List the tasks on the worksheet, WBS number, and task description 2. List the dependencies of each task 3. Record the duration of each task 4. Calculate the early start date and early finish date for each task, beginning with i = min (task #) {

• Early finish date of the ith task = early start date + duration • Early start date of the (i+1)th task if dependent on other task i = (the early finish date of task i) + 1 • Set i = i + 1}

5. Calculate the late start date and late finish date for each task, beginning with i = max (task #) { • Late start date of the ith task = late finish date – duration • Late finish date of the (i-1)th task if the ith task depends on the (i-1)th task = (the late start date of task i) – 1 • Set i = i – 1}

6. Calculate float for each task where float = late start date – early start date 7. Determine the critical path for the project by adding up the duration of every task with zero float

• Task # 1, 4, 5, 6, and 7 are the critical path task and their durations total 144 days
