*Knowing What the Project Is:Planning Fundamentals
“Failing to plan is planning to fail.” - Harold Kerzner
If project deliverables are clear, much of the work can be pre-planned (Linear Project Life Cycle approach)
If project deliverables are not clear, initial work should focus on a set of deliverables that will either provide clarity in the scope or are pre-agreed upon (Iterative, Adaptive, Extreme Project Life Cycle approaches)
The more uncertain the deliverables, the greater the need is for frequent “validation cycles”
Do detailed planning only up to the next point of knowledge
![Page 8: Project Management (x470)](https://reader035.vdocuments.site/reader035/viewer/2022062302/568163d4550346895dd51fba/html5/thumbnails/8.jpg)

*Project Life Cycle Approaches
Q1: Linear Approacho Low complexityo Well understood
technologyo Low risko Completed similar

Q2: Adaptive / Iterative Approacho Product development
and process improvement
o Production prototype development
Q4: Unlikely Situation
Solution looking for a problem
Q3: Extreme Approacho Nothing about the
project is certaino Product is accepted
after some iterations or pulls plug

Rolling wave planning – progressive detailing of the project plan that indicates iterative and ongoing nature of planning. Near-term deliverables identified at a low-level view of detail, long-term deliverables identified at a high-level view of detail (Iterative, Adaptive, Extreme Life Cycle Approaches)

*Knowing What the Project Is:Decomposition
* Subdivision of major project deliverables or sub-deliverables into smaller, more manageable components until the deliverables are defined in sufficient detail to support development of project activities (planning, executing, etc..)
Identify major project deliverablesDecide if adequate cost and duration estimate can be made at this level of detail for each deliverableIdentify constituent components of the deliverable if necessaryVerify correctness of decomposition (necessity, definition, cost, duration, responsibility)
Definition: Steps:

*Knowing What the Project Is:Work Breakdown Structure
A deliverable oriented grouping of project components that organizes and defines the total scope of the projectDefines products, not tasksCan be developed using a top-down or bottom-up approachCan be hardware-related, function-related, life cycle-related or a combination
Foundation of all planning!

*Knowing What the Project Is:Requirements ChallengesMay not be fully known at the start of a projectMay come from multiple sources / groupsMay come at various levels of detailsSome stakeholders may not be known initiallyMay be “wants” and not “needs”
Wants - usually more associated with a solutionNeeds - usually more associated with the underlying problem
May conflict with each other May feed off each otherUsually requires iterations and trade-offs to finalizeMay change

*Knowing What the Project Is:Scope Determination Summary
Make sure project stakeholders have all been identifiedFunctional groups that will have a deliverable on the project should be represented on the project teamWBS should represent only the work needed to complete the project successfullyValidate the Scope baseline documents with the project sponsor or approving authorityProcess iteration is the norm

*Knowing What the Project Is:Critical Path and Float
Critical PathLongest time span through the total system of activities / eventsDelay in any activity / task in the critical path delays the whole projectImprovement in total project time means reducing time for activities / events in the critical path
Slack Time (Float) - Time differential between the scheduled completion date and the required date to meet critical path.
![Page 50: Project Management (x470)](https://reader035.vdocuments.site/reader035/viewer/2022062302/568163d4550346895dd51fba/html5/thumbnails/50.jpg)
50
*Knowing What the Project Is:Critical Path Calculation*Determined by doing forward and backward pass calculations
Forward Pass• Calculates early start and
early finish dates• Project end date• Longest path
Backward Pass• Calculates late start and
late finish dates• Task / project float• Identifies tasks in critical
path
![Page 51: Project Management (x470)](https://reader035.vdocuments.site/reader035/viewer/2022062302/568163d4550346895dd51fba/html5/thumbnails/51.jpg)
51
*Knowing What the Project Is:Forward Pass
The first predecessor task(s) have an Early Start (ES) of zeroEarly Finish (EF) dates are calculated by adding the task duration (TD) to the earliest date (ES) a task can startThe EF date of the predecessor becomes the ES date for the successorWhen there are multiple predecessors, ES is the larger of the EFs for the task
![Page 52: Project Management (x470)](https://reader035.vdocuments.site/reader035/viewer/2022062302/568163d4550346895dd51fba/html5/thumbnails/52.jpg)
52
*Knowing What the Project Is:Backward Pass
Late Start (LS) and Late Finish (LF) dates are calculated starting from the end of the projectLS is calculated by subtracting the TD from the LF of the taskLS for the successor task becomes the LF for the predecessor taskWhen there are multiple successors, LF is the smaller of the LSs
![Page 53: Project Management (x470)](https://reader035.vdocuments.site/reader035/viewer/2022062302/568163d4550346895dd51fba/html5/thumbnails/53.jpg)
53
*Knowing What the Project Is:Critical Path and Float
Task Float = Late Finish – Early FinishThose tasks with zero float are on the critical path

*Knowing What the Project Is:Schedule Development Considerations
* Life Cycle Approach*Constraints
–Imposed dates on activities (start/finish)–Key events / major milestones
* Leads and lags: dependency relationship among activities
* Schedule compression–Crashing–Fast Tracking

*Knowing What the Project Is:Cost Planning Steps
Objective: Identify the funding needed to meet project goals / deliverables.
•WBS•Resource Plan•Project Schedule
Determine Budget
Work Package cost estimate
•Project budget estimate•Cost Baseline
Estimate Cost

61
*Knowing What the Project Is: Analogous Estimating*Use actual cost of a previous similar
project to estimate cost of current project*Approximate (rule of thumb) estimate*Made without any detailed engineering
data*Top-down estimating*Accuracy +- 15%
![Page 62: Project Management (x470)](https://reader035.vdocuments.site/reader035/viewer/2022062302/568163d4550346895dd51fba/html5/thumbnails/62.jpg)
62
*Knowing What the Project Is:Parametric Modeling*Use project parameter in a mathematical
model to predict project cost*Made without any detailed engineering data*Order of magnitude estimate*May use past experience*Accuracy +- 35% within the scope of the
project*Example: construction cost per square foot
![Page 63: Project Management (x470)](https://reader035.vdocuments.site/reader035/viewer/2022062302/568163d4550346895dd51fba/html5/thumbnails/63.jpg)
63
*Knowing What the Project Is:Bottom-Up Estimating
*Cost estimate of WBS work packages rolled up to a project total *Definitive/detailed estimate*Prepared from well-defined engineering data,
vendor quotes, unit prices, etc. *Accuracy +- 5%

*Knowing What the Project Is:Current Costing Practice
*Shows monthly cash flow*Identifies capitalized vs. operating

67
*Knowing What the Project Is:Planning Best Practices Summary*Determine appropriate project life cycle approach
* Use Scope Statement / WBS to baseline project scope*Develop a project schedule to baseline project time*Develop a cost baseline * Focus is more on “knowing what the project is”* Partner with line managers to get agreement on scope,
time and cost baselines* Change control process should be in place as soon as
possible* Validate progressive elaboration outputs
