• Prepared presentation• Articulates in 3-4 minutes

• Who are you helping• With what problem• How company benefits

• Practicing is a good idea

Prioritization

• Waterfall• Timing determines likelihood• Developers instead of customer

• Agile• Value determines likelihood• Reassessed throughout project

Alternatives review & decision

There may be multiple ways to fulfill the Requirements

1. Eliminate alternatives that don’t meet external constraints

2. Evaluate remaining alternatives against selected criteria:• time/budget requirements• Team skillset and interest• Other criteria as team requires

PMBOK: process to create project schedule:

Process Output

Activity Definition Detailed WBS; activity lists

Activity sequencing Project Network Diagrams

Activity Duration Estimation

Activity Duration Estimates

Schedule Development Project Schedule

These processes can be combined, and iterative, if need be

Work Breakdown Structure• “A hierarchical description of the work that

must be done to complete the project as defined in the Project Overview Statement.”

• Inputs• POS• Requirements Document

• Terms• Activity: Chunk of work• Tasks: Smaller chunk of work. Activities are

made up of tasks• Work Package: Complete description of how the

tasks that make up the activity will actually be done

Page 16: Effective Project Management Barbara Stone September 27, 2007.

Uses for the WBS

• Thought Process Tool• Architectural Design Tool• Planning Tool • Project Status Reporting Tool

Activity DefinitionDecomposing the task areas / sub-projects

‘tasks in appropriate level of detail’ – what does this mean for your project? Think about:

• experience of your team

• possibly duration of task

• # of people performing the task: if hand-off, new task

• Only needs single person to oversee work

Team creating the WBS should have appropriate level of expertise to assign approximate duration to each task(because they will, later).

Page 20: Effective Project Management Barbara Stone September 27, 2007.

Brainstorming

Recorder – writes all ideas where visible to team

• Allows people to build on others ideas

• Participant knows his/her contribution is valuable & heard

Facilitator• All ideas accorded

consideration – no editing

• keeps discussion focused

• Sets time limits

Mind-mapping – user story nodes

Adding task details

Page 24: Effective Project Management Barbara Stone September 27, 2007.

24

Tips• Person who has experience in doing something

similar better at defining sub-tasks and duration. No team member with experience? Adds to risk & needs safety Try to get someone with experience to help with planning if you cannot have them on the team for execution

• May not know all detail – as work through the plan and the project, scope will shift – hopefully only slightly

Page 25: Effective Project Management Barbara Stone September 27, 2007.

25

Activity SequencingProcess of determining both order and possible

overlap of tasks - start with task constraints

Examples:• Task A needs to be complete before task B may

start

• Tasks C, D, & E may be done in parallel, but all must be complete before task F may begin

• Task X may not begin until milestone Y has occurred

• Task Q must start at the same time as task R

PERT – activity on arc

Activity duration estimating

An art, with a little bit of science

Best estimators are those who have done similar work

Beware of confusing duration and effort

“The duration of most activities will be significantly influenced by the resources assigned to them”

Page 29: Effective Project Management Barbara Stone September 27, 2007.

PMBOK: Activity Duration Estimating

Inputs

1. Activity List

2. Constraints

3. Assumptions

4. Resource Requirements

5. Resource capabilities

6. Historical information

7. Identified risks

Tools/Techniques

1. Expert judgment

2. Analogous estimating

3. Quantitatively based

durations

4. Reserve time

(contingency = safety)(contingency = safety)

Outputs

1. Activity duration estimates2. Basis of estimates3. Activity list update

Page 30: Effective Project Management Barbara Stone September 27, 2007.

Pert (one network diagram technique)

Formula Task Duration

• O = most optimistic estimate

• M = most likely estimate

• P = most pessimistic estimate

O+4M+P6

Sample

You’ve been infected with spy wear and suspect it’s a root kit – have to do a clean install

36

Six Criteria to Test for WBS Completeness

• Status/Completion is measurable• The activity is bounded• The activity has a deliverable• Time and cost are easily estimated• Activity duration is within acceptable limits• Work assignments are independent

Seventh Criteria – Project manager’s judgment that the WBS is not complete

Page 37: Effective Project Management Barbara Stone September 27, 2007.

37

Exceptions to the Completion Criteria Rule

• Stopping Before Completion Criteria Are Met

• Decomposing Beyond Completion of the Criteria

Page 38: Effective Project Management Barbara Stone September 27, 2007.

38

Factoring in constraints

• Factor if multiple working on task together? – discuss XP example.

• Also factor if do not have resource 100% of time. Why this is a bad idea.

• Adding ‘Project Management’ factor

• Do Jodie and Barbara do this?

Page 39: Effective Project Management Barbara Stone September 27, 2007.

Putting it all together

Tasks

+ Duration

+ Sequencing

+ Start date

= Project Schedule

Does it meet Deadline / Scope / $ constraints?

Page 40: Effective Project Management Barbara Stone September 27, 2007.

Gantt chart

• Does not show task interdependencies or resources assigned

• Do not help organize project as effectively as WBS & network diagrams

• Completed after WBS• Effectively show progress & time

Common scheduling pitfalls

• Planned downtime – calendar events, team needs

• External interfaces – contractors, external teams

• Constraints – duration, access, etc.• Time to come up to speed• 100% optimization• Just plain missed it
