Software Project Management
  • Session 9 Project Control

2
Today
  • Session 8 Review
  • Project Control
  • Status Reporting
  • Earned Value Analysis
  • MS Project

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

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

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 theres one or more areas under
    closer scrutiny
  • Status Reporting
  • Part of the communications management plan
  • Which is usually just a section of SDP

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
Programming Status Reporting
  • A programmer reports that hes 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 cant measure scope or quality you dont
    know reality
  • You really only know cost (hours spent)
  • How can you improve this?

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
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
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
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
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
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
Earned Value Analysis
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
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 lt 1, EAC will be gt BAC
  • CR Critical Ratio
  • SPI x CPI
  • 1 everything on track
  • gt .9 and lt 1.2 ok
  • Can be charted

19
EVA Example
  • As of 1-July where are we?
  • BCWS
  • BCWP
  • ACWP

20
EVA Example
  • CV
  • SV
  • CPI
  • SPI
  • CR

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

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
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
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
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

26
Project UI
27
Create Your Project
  • File/New
  • Setup start date
  • Setup calendar
  • Menu Project/Project Information
  • Often left with default settings
  • Hours, holidays

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 dont
    most of the time

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
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
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
Effort-Driven Scheduling
  • MS-Project default
  • Duration Units Work
  • Duration Work / Units (D W/U)
  • Work Duration Units (W DU)
  • 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
Link Tasks
  • On toolbar Link Unlink buttons
  • Good for many at once
  • Or via Gantt chart
  • Drag from one task to another

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

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

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

38
