Today
• Session 8 Review
• Project Control
• Status Reporting
• Earned Value Analysis
• MS Project

3. 3
Session 8 Review
• Project roles and team structure
• CMM
• Requirements

4. 4
Project Control
• Ongoing effort to keep your project on track
• 4 primary activities:
– 1. Planning performance
• A SDP, schedule, and a control process
– 2. Measuring status of work performed
• Actuals
– 3. Comparing to baseline
• Variances
– 4. Taking corrective action as needed
• Response
• Prerequisite to good control is a good plan

5. 5
Project Control
• “Control”
• Power, authority, domination. No.
• Guiding a course of action to meet an objective. Yes.
• Principles
• Work is controlled, not workers
– Control helps workers be more effective & efficient
• Control based on work completed
– Use concrete deliverables
• Balance
– Appropriate level between too much and too little
– Includes:
» Micro-managing vs. neglect
» Too much tracking detail vs. too little

6. 6
Progress Monitoring
• The 3 key Progress Monitoring Questions
– What is the actual status?
– If there’s a variance, what is cause?
– What to do about it?
• Possible responses
• 1. Ignore
• 2. Take corrective action
• 3. Review the plan

7. 7
Progress Monitoring
• Monitoring rates
– Daily, weekly, monthly
– If problems occur – then adjust
• You may have to monitor problem areas more closely
• For some period of time
• Almost always there’s one or more areas under closer scrutiny
• Status Reporting
– Part of the communications management plan
– Which is usually just a section of SDP

8. 8
Status Reports
• From team to PM, from PM to stakeholders
• Typical format for latter
– Summary
– Accomplishments for this period (done)
• Tasks, milestones, metrics
– Plans for next period (to-do)
– Risk analysis and review
– Issues & Actions
• Shoot for weekly updates
– Email notes, then hold brief meeting
– More frequently during crises

9. 9
Programming Status Reporting
• A programmer reports that he’s 90% done.
– What does this mean?
• A programmer reports completing 4,000 LOC on
estimated 5,000 LOC effort.
• Is this 80% complete?
• Quality?
• Ratio, estimated to completed?
– Your estimates could have been wrong
• If you can’t measure scope or quality you don’t know “reality”
• You really only know cost (hours spent)
• How can you improve this?

10. 10
Binary Reporting
• Work packages (tasks) can only be in one of 2
states: complete or incomplete
– No partial credit
• Preferred to anything subjective!
• “90% Complete Syndrome”
– Software is 90% complete 90% of the time
• Use lower-level task decomposition
• Tangible exit criteria
• Plan for 4-80 staff hours of effort per task

11. 11
Earned Value Analysis (EVA)
• a.k.a. Earned Value Management (EVM)
• a.k.a. Variance Analysis
• Metric of project tracking
• “What you got for what you paid”
– Physical progress
• Pre-EVA ‘traditional’ approach
• 1. Planned time and costs
• 2. Actual time and costs
• Progress: compare planned vs. actual
• EVA adds third dimension: value
• Planned, actual, earned

12. 12
Earned Value Analysis
• Forecasting
– Old models include cost & expenditure
– EVA adds schedule estimation
• Measured in dollars or hours
– Often time used in software projects
• Performance Measurement Baseline (PMB)
• Time-phased budget plan against which contract performance
is measured
• Cost & schedule variances go against this
• Best via a bottom-up plan

13. 13
Earned Value Analysis
• Different methods are available
– Binary Reporting
– Others include
• Based on % complete
• Weights applied to milestones
• EVA can signal errors as early as 15% into
project
• Alphabet Soup

14. 14
Earned Value Analysis
– 3 major components
• BCWS: Budgeted Cost of Work Scheduled
– Now called “Planned Value” (PV)
– “Yearned”
– How much work should be done?
• BCWP: Budgeted Cost of Work Performed
– Now called “earned value” (EV)
– “Earned”
– How much work is done?
– BCWS * % complete
• ACWP: Actual Cost of Work Performed
– Now called “Actual Cost” (AC)
– “Burned”
– How much did the work done cost?

15. 15
Derived EVA Variances
• SV: Schedule Variance
– BCWP – BCWS
– Planned work vs. work completed
• CV: Cost Variance
– BCWP – ACWP
– Budgeted costs vs. actual costs
• Negatives are termed ‘unfavorable’
• Can be plotted on ‘spending curves’
– Cumulative cost (Y axis) vs. Time (X axis)
– Typically in an ‘S’ shape
• “What is the project status”?
– You can use variances to answer this

16. 16
Earned Value Analysis

17. 17
Derived EVA Ratios
– SPI: Schedule Performance Index
– BCWP / BCWS
– CPI: Cost Performance Index
– BCWP / ACWP
– Problems in project if either of these less than 1
(or 100%)

18. 18
Earned Value Analysis
• Other Derived Values
• BAC: Budget At Completion
– Sum of all budges (BCWS). Your original budget.
• EAC: Estimate At Completion
– Forecast total cost at completion
– EAC = ((BAC – BCWP)/CPI) + ACWP
– Unfinished work divided by CPI added to sunk cost
– If CPI < 1, EAC will be > BAC
• CR: Critical Ratio
– SPI x CPI
– 1: everything on track
– > .9 and < 1.2 ok
– Can be charted

21. 21
Earned Value Analysis
• BCWS
– Use ‘loaded labor’ rates if possible
• Direct pay + overhead
• Remember it’s an aggregate figure
– May hide where the problem lies
– Beware of counterbalancing issues
• Over in one area vs. under in another

22. 22
Earned Value Analysis
• Benefits
– Consistent unit of measure for total progress
– Consistent methodology
• Across cost and completed activity
• Apples and apples comparisons
– Ability to forecast cost & schedule
– Can provide warnings early
• Success factors
– A full WBS is required (all scope)
– Beware of GIGO: Garbage-in, garbage-out

23. 23
The MS-Project Process
• Move WBS into a Project outline (in Task Sheet)
• Add resources (team members or roles)
• Add costs for resources
• Assign resources to tasks
• Establish dependencies
• Refine and optimize
• Create baseline
• Track progress (enter actuals, etc.)

24. 24
Project Overview
• This is a ‘quickie’ overview
• We will return to all of these steps
individually over the next few weeks
• Sample project from McConnell

25. 25
Project UI
• Views
– Default is Gant Chart View
• 2 panes
• Task Sheet on left (a table)
• Gantt Chart on right
– View Bar on far left

27. 27
Create Your Project
• File/New
• Setup start date
• Setup calendar
– Menu: Project/Project Information
– Often left with default settings
– Hours, holidays

28. 28
Enter WBS
• Outlining
• Sub-tasks and summary tasks
• Do not enter start/end dates for each
• Just start with Task Name and Duration for each
• Use Indent/Outdent buttons to define summary
tasks and subtasks
• You can enter specific Start/End dates but don’t
most of the time

29. 29
Establish Durations
• Know the abbreviations
– h/d/w/m
– D is default
• Can use partial
– .5d is a half-day task
• Elapsed durations
• Estimated durations
– Put a ‘?’ after duration

30. 30
Add Resources
• Work Resources
– People
• Material Resources
– Things
– Can be used to track costs
• Ex: amount of equipment purshased
– Not used as often in typical software project

31. 31
Resource Sheet
• Can add new resources here
– Or directly in the task entry sheet
• Beware of mis-spellings (Project will create near-duplicates)
• Setup costs
– Such as annual salary (put ‘yr’ after ‘Std. Rate’)

32. 32
Effort-Driven Scheduling
• MS-Project default
• Duration * Units = Work
• Duration = Work / Units (D = W/U)
• Work = Duration * Units (W = D*U)
• Units = Work / Duration (U = W/D)
• Adding more resources to a task shortens duration
• Can be changed on a per-task basis
• In the advanced tab of Task Information dialog box
• Task Type setting
• Beware the Mythical Man-month
• Good for laying bricks, not always so for software
development

33. 33
Link Tasks
• On toolbar: Link & Unlink buttons
– Good for many at once
• Or via Gantt chart
– Drag from one task to another

34. 34
Milestones
• Zero duration tasks
• Insert task ‘normally’ but put 0 in duration

35. 35
Make Assignments
• Approach 1. Using Task Sheet
– Using Resource Names column
– You can create new ones by just typing-in here
• 2. Using Assign Resources dialog box
– Good for multiple resources
– Highlight task, Tools/Resources or toolbar button
• 3. Using Task Information dialog
– Resources tab
• 4. Task Entry view
– View/More Views/Task Entry
– Or Task Entry view on Resource Mgmt. toolbar

36. 36
Save Baseline
• Saves all current information about your project
– Dates, resource assignments, durations, costs

37. 37
Fine Tune
• Then is used later as basis for comparing against
“actuals”
• Menu: Tools/Tracking/Save Baseline

38. 38
