Coming up: Project Management
– 4 Ps

Why care about project
management?
 10% of projects successful between 1998 and 2004

Project Management – 4 Ps
 People — the most important element of a
successful project
 Product — the software to be built
 Process — the set of framework activities and
software engineering tasks to get the job done
 Project — all work required to make the product a
reality
Coming up: Stakeholders are people to

Stakeholders are people too
 Senior managers who define the business issues that often have
significant influence on the project.
 Project (technical) managers who must plan, motivate, organize,
and control the practitioners who do software work.
 Practitioners who deliver the technical skills that are necessary to
engineer a product or application; often make poor team leaders
 Customers who specify the requirements for the software to be
engineered and other stakeholders who have a peripheral interest
in the outcome.
 End-users who interact with the software once it is released for
production use.
Coming up: Your job as a leader
Your job is to organize and bring value from these people

Your job as a leader
 The MOI Model
 Motivation. The ability to
encourage (by “push or pull”)
technical people to produce to their best ability.
 Organization. The ability to mold existing
processes (or invent new ones) that will enable the
initial concept to be translated into a final product.
 Ideas or innovation. The ability to encourage
people to create and feel creative even when they
must work within bounds established for a particular
software product or application.
Coming up: Your job as a manager

Your job as a manager
Make sure these happen
 Formal risk management
 Empirical cost and schedule estimation
 Metrics-based project management
 Tracking – amount of work done, costs, work
remaining, etc…
 Defect tracking against quality targets
 People aware project management
Coming up: Project Manager

Project Manager
 Management is using tools and
techniques
 Leadership is inspiring people to do the
right thing
 Leadership with poor management
practices can be successful, management
with poor leadership will fail.
Coming up: Motivating People

Motivating People
 Use monetary rewards cautiously
 Use intrinsic rewards
 Recognition
 Achievement
 The work itself
 Responsibility
 Advancement
 Chance to learn new skills
Coming up: Understanding the problem

Understanding the problem
At the beginning you should ask yourself these questions
 Why is the system being developed?
 What will be done?
 When will it be accomplished?
 Who is responsible?
 Where are they organizationally located?
 How will the job be done technically and
managerially?
 How much of each resource (e.g., people, software,
tools, database) will be needed?
Barry Boehm
Coming up: Define success and failure

Define success and failure
 Don’t lie to yourself!
 Be confident, trust
yourself for success!
 Quantify your project
outcomes to allow
success or failure
 A vague or un-measurable outcome is much
less helpful - Dan Fleck
Coming up: Leadership Case Study: 3M

Leadership Case Study: 3M
Philosophy:
 As our business grows, it becomes increasingly necessary to delegate
responsibility and to encourage men and women to exercise their initiative.
This requires considerable tolerance. Those men and women to whom we
delegate authority and responsibility, if they are good people, are going to
want to do their jobs in their own way.
 "Mistakes will be made. But if a person is essentially right, the mistakes he
or she makes are not as serious in the long run as the mistakes
management will make if it undertakes to tell those in authority exactly how
they must do their jobs.”
 "Management that is destructively critical when mistakes are made kills
initiative. And it's essential that we have many people with initiative if we
are to continue to grow." .
 These are common themes now, but not in 1940s when 3M codified them
Coming up: 3M Results

3M Results
 Encouragement and a culture of innovation
yields:
 1968 Dr. Spence Silver does an experiment that yields an adhesive that sticks, but not strongly
 Presents around the company for 5 years with no “takers”
 In 1973, 3M scientist Art Fry was trying to mark his place in his church choir hymn book with
bits of paper that kept falling out.
 Art works with Spence. Creates little notepapers.
 Marketing says “not enough market, who wants to pay for scraps of paper?”, engineering says
“too hard to make, will be costly”
 Response: If it’s hard to make that’s great, no one but 3M will be able to do it!
 Fry sends out “free samples” across the company, making sure to include executive’s
assistants
 Demand rises – finally the product is introduced. Within 1 year PostIt notes named “Outstanding
New Product” and today generates $100 million in US sales
 This is possible because of a culture in the company to empower, encourage, and experiment!
Coming up: Avoid team toxicity

Scheduling
 One of the most
important things you
can do is schedule.
 Also one of the first things you should do!
 Tools help
 Microsoft Project
 OpenProj.org
 OpenWorkbench.org
Coming up: Planning

Planning
 The bad news: time flies
 The good news: you’re the pilot!
 You must begin planning
immediately
 Given limited information
 Plan anyway and then
revise
Coming up: Creating a plan: Things to know

Creating a plan: Things to know
 Scope
• Context. How does the software to be built fit into a larger system,
product, or business context and what constraints are imposed as a
result of the context?
• Information objectives. What customer-visible data objects
(Chapter 8) are produced as output from the software? What data
objects are required for input?
• Function and performance. What function does the software
perform to transform input data into output? Are any special
performance characteristics to be addressed?
 Software project scope must be unambiguous and
understandable at the management and technical
levels.
Coming up: Creating a plan: Things to do

Creating a plan: Things to do
 Problem Decomposition: Sometimes called
partitioning or problem elaboration
 Once scope is defined …
 It is decomposed into constituent functions
 It is decomposed into user-visible data objects
or
 It is decomposed into a set of problem classes
 Decomposition process continues until all
functions or problem classes have been defined
(this won’t be far at the beginning of your
project)
Coming up: Create a schedule

Schedule
 List of tasks
 With dates
 With assigned resources (people)
 With durations
 With predecessors and successors
 How do you get buy-in from the team for a
schedule?
 History
 Increments
Coming up: Schedule Terms

Schedule Terms
 Critical path
 Sequence of tasks that form the longest path to
completion of the project. Any delay on any of these
will make the overall completion date move.
 Slack
 Amount of time a task can be delayed without
affecting the overall completion date.
• Start slack - amount before task needs to start
• Finish slack - amount before task needs to finish
 Milestone - An import date in the schedule
 Dependencies - relationship between tasks
Coming up: Schedule Dependencies

Schedule Dependencies
 FS - Finish to start (most common)
 A FS B. B doesn’t start until A is finished
 Build wall FS Paint wall
 FF - Finish to finish
 A FF B. B doesn’t finish before A is finished
 Write final chapter FF Complete Index
 SS - Start to start
 A SS B. B doesn’t start until A has started
 Project funded SS project management activities begin
 SF - Start to finish
 A SF B. B doesn’t finish before A has started
 Once A starts, B is allowed to finish
 B=Baby sit a child, A=parent comes home
Coming up: Resource Leveling

Resource Leveling
 A process to examine a project for an unbalanced
use of people and to resolve over-allocations or
conflicts
 Happens when multiple tasks are scheduled at the
same time for the same person
 Solution:
 Make tasks sequential by introducing “fake”
dependencies
 Split resource usage among tasks (50% on task 1, 50%
on task 2)
Coming up: Auto Resource Leveling

Auto Resource Leveling
 Some tools (not Open Project) provide auto
resource leveling
 Tool automatically ensures no person works
over 100% of the time (automatically makes
tasks sequential)
 Advantageous because this does not
introduce “fake” dependencies
Coming up: Gantt Chart

Gantt Chart
Coming up: Finding Critical Path

Finding Critical Path
 Draw a network diagram of the activities
 Determine the Early Start (ES) of each
node. Work from beginning node (ES=0)
to final node
 ES - earliest time the activity can start
 ES = Max(ESprevNode + DurationPrevNode)
Coming up: Finding Critical Path

ES: 4
ES: 2
ES: ??

Finding Critical Path
 Determine the Late Start (LS) of each
node. Work from the final node to the
beginning node.
 The latest time the activity can start without
changing the end date of the project
 LS = MIN(LSnext - DurationNode)
 For the last node LS = ES

Coming up: Earned Value Management

Scheduling Rules of Thumb
 One person should always edit the
schedule (you!)
 If you have two people that need to, create
two files and link them together
 Keep it simple and useful
 Level your resources
 Share the schedule with your team
 40-20-40; coding is 20% of the effort

Scheduling Steps
 Add in all the tasks (preferably in a
hierarchy)
 Add in all the dependencies
 Break down large tasks into smaller tasks.
Optimally (in Dan Fleck’s opinion) you want
to schedule so the duration of each smallest
task is at most 3-5 days
 Assign people (resources) to tasks
 Level your resources
Coming up: Classic Mistakes

Classic Mistakes
 Overly optimistic schedule
 Failing to monitor schedule
 Failing to update schedule
 Adding people to a late project
 Failure to manage expectations of others
 Leaving out a task
Coming up: Scope Creep

Earned Value Management
 How much work you planned to have accomplished by
now (in dollars or hours) called the Planned Value
 How much you have actually spent by now (in dollars or
hours), called Actual Cost
 The value, in terms of your baseline budget, of the work
accomplished by now (in dollars or hours), called the
Earned Value!
Coming up: Earned Value Management
Idea is to link schedule and cost together to
monitor both in the same “units” of value

 Planned value (PV) - the value of all resources
needed to meet the project’s objectives
 Each objective of a project has an associated
planned value
 Budgeted (cost) at completion (BAC) - The sum
of all the PVs
 Earned value (EV) - the amount of value
completed at any point during the project
 Actual Cost (AC) - actual amount of money you
have spent so far. In a perfect project AC and
EV are the same.
Coming up: Earned Value Management Example

Example
 We’ve budgeted $200 to buy, setup, network
and test a new system
 Our planned values (PVs) of each task are:
• Buy - $50, Setup - $75, network - $50, test - $25
• Our BAC is therefore $200
 We’ve now completed phase one, and thus our
earned value (EV) is now $50.
 To do this we spent $60 (our actual cost (AC))
Coming up: Earned Value Management Example

Example
 Schedule performance index (SPI)
 EV / PV --> 50/50 = 1 (perfect).
 Our group is on schedule
 Cost performance index (CPI)
 EV / AC --> 50/60 = 0.83
 For every dollar spent, I get 83 cents worth of work.
 Estimated cost at completion (EAC)
 BAC / CPI = 200 / 0.83 = $240.96
 Schedule Variance (SV) : EV - PV
 Cost Variance (CV) : EV - AC
Coming up: EVM Example 2 from: http://www.hyperthot.com/pm_cscs.htm
Memorization
Hint: Most
equations begin
with earned value

EVM Example 2 from:
http://www.hyperthot.com/pm_cscs.htm
 PLANNED VALUE (Budgeted cost of the work scheduled)
= 18 + 10 + 16 + 6 = $50
 EARNED VALUE (Budgeted cost of the work performed)
= 18 + 8 + 14 + 0 = $40
 ACTUAL COST (of the work performed) = $45 (Data from Acct.
System)
 Therefore:
 Schedule Variance = 40 - 50 = -$10
 Schedule Performance Index = 40 / 50 = 0.8
Coming up: What is earned value?
What is planned value at time X?
What is earned value at time X?

Earned – Planned. Perfect is?

What is earned value?
 A. The amount of money you get upon
completion of a task
 B. The value of an activity
 C. The value of the work completed by
now in the schedule
 D. The value of all activities planned to be
completed by now in the schedule
Coming up: Why do you use earned value management?

Why do you use earned value
management?
 A.It is required by my contract
 B. Measuring value give you more
information than measuring cost or time
alone
 C. I don’t use it
 D. It guarantees my project will be done
on time
Coming up: Scheduling Rules of Thumb

Scope Creep
 The scope of your project is all the work you
initially planned to do.
 Scope creep is when your project gets new
tasks throughout it’s lifetime without adding
more resources to handle new tasks. The
scope is “creeping” up…
 Scope changes are OK, and really
unavoidable… that’s fine. However you must
update the resources (time, features or
people accordingly)
Coming up: Why would scope changes occur?
Scope
BOO!

Why would scope changes
occur?
 A. You get more money to do more things
 B. The customer asks you to do
something extra because “it is critical for
success”
 C. A competing product has a feature that
you must have to be competitive
 D. All of these
Coming up: Which are causes of scope creep?

Scope Change versus Creep
Your company has a $1million dollar
contract with a defined scope.
Scope change:
Customer: please add all these requirements,
and I’ll increase the contract to $2million dollars
Manager: Certainly! 
Scope creep:
Customer: please add all these requirements, and I’ll be
really happy.
Manager: Certainly! 
Change is good!

Which are causes of scope creep?
 A. poor change control
 B. lack of proper initial identification of
what is required to satisfy project
objectives
 C. a weak project manager
 D. all of these
Source: Wikipedia: Scope Creep
Coming up: Managing Scope

Managing Scope
 How to deal with the inevitable “Scope
creep”?
 Joint Application Development and
prototyping
 Formal change approval
 Defer additional requirements as future
system enhancements

Coming up: Managing Risk

Managing Risk
 Document your risks in a risk management plan
1 Description of risk
2 Likelihood of occurrence (0-100%)
3 Impact - 1(low)  5 (high), or cost $20,000
4 Exposure = Impact * Likelihood
5 Mitigation strategy
• How to lessen the impact of the risk
• How to lessen the likelihood
• An action plan if risk occurs
 Update and track your risks
 Communicate your risks to upper management
Coming up: Projects get into trouble when…

Coming up: Common-Sense Approach to Projects
Projects get into trouble when…
 Software people don’t understand their customer’s needs.
 The product scope is poorly defined.
 Changes are managed poorly.
 The chosen technology changes.
 Business needs change [or are ill-defined].
 Deadlines are unrealistic.
 Users are resistant.
 Sponsorship is lost [or was never properly obtained].
 The project team lacks people with appropriate skills.
 Managers [and practitioners] avoid best practices and lessons
learned.

Coming up: References
Common-Sense Approach to Projects
 Start on the right foot. This is accomplished by working hard (very hard) to
understand the problem that is to be solved and then setting realistic
objectives and expectations.
 Maintain momentum. The project manager must provide incentives to
keep turnover of personnel to an absolute minimum, the team should
emphasize quality in every task it performs, and senior management
should do everything possible to stay out of the team’s way.
 Track progress. For a software project, progress is tracked as work
products (e.g., models, source code, sets of test cases) are produced and
approved (using formal technical reviews) as part of a quality assurance
activity.
 Make smart decisions. In essence, the decisions of the project manager
and the software team should be to “keep it simple.”
 Conduct a postmortem analysis. Establish a consistent mechanism for
extracting lessons learned for each project.
