Creating a WBS
--------------
1. Decomposition - Breaking down tasks until a task can be understood/completed by one resource.
2. Rolling Wave Planning - Requirement clarity leads to expansion of task in WBS.
3. Templates - PMO (or other resources) may provide templates for WBS to use (Created from other projects).
4. Expert Judgement (experience wisdom)
Techniques for Activity Sequencing
----------------------------------
These techniques can also act as controls for managing schedule.
PDM -
FS - To start current task finish the predecessor.
FF - To finish current task predecessor must finish
SS - To start current task predecessor must have started.
SF - To finish current task the previous task should have started.
..
Dependency Determination
..Mandatory (required)
..Discretionary (optional)
..External (have no ctrl over the resources)
Leads and Lags
..Activities added in WBS to either accelerate or decelerate a project.
..Lead by starting multiple things with dependencies
together.
Schedule Network Templates
Detailed analysis of multiple PDM's to find area for optimizing schedule.
1. Getting rid of activities that are redundant.
2. Starting activities (that do not have a dependency) earlier
Time estimation
---------------
1. Expert Judgement
2. Analogous Estimation
Carpet installation
Input factors for estimation are well known.
Applied for other projects and can be used time and again.
3. Parametric Estimation
Similar to Analogous with .. several templates have been designed and tested.
Provides alternative approaches for estimation to calculate schedule.
4. Three Point Estimate
Optimisitc
Pessimistic
Most Likely
(opt + 4 * mostlikely + pess)/6
5. Reserve Analysis.
Contingency reserves requirement.
Assigning Resources
1. In a word document list job titles needed for each task.
PM1 - Project Manager 1 - $135.00 ph
PM2 - Project Manager 2 - $135.00 ph
SE1 - Software Engineer 1 - $25.00 ph
..
Checklist
15 items in WBS with activity sequencing
Durations for each task (not milestone) in days.
No questions mark next to days entry.
Resources assigned based on your Resource worksheet.
Go to Row 1 - Add a milestone - Franchising Project
Select Row 2 thru 16 and indent it below Franchising Project.
What are some things to keep in mind when assigning resources?
1. Skills to tasks
2. Resource time to project schedule.
3. Resource calendar
Finally - its time to create a schedule.
Page 154 -
1. Schedule Network Analysis - Analyze dependencies and eliminate redundant tasks or dependencies.
2. Critical Path Method (applies to tasks with mandatory dependencies)
Theoretical
early start and finish dates
late start and late finish
forward pass on plan / backward pass on the plan
Idea of start/end dates for each activity.
Output - An estimate of total project duration being mindful of early start and finish dates & late start and late finish dates.
List of all activities with Strong predecessors that must be completed to finish the project.
3. Critical Chain method
MS Project - modify the project schedule and adjust it to account for overallocated resources.
Reviewing tasks with strong dependencies that may have inadequate resource allocation.
Fixing the above issue(s) on a per task basis.
4. Resource Leveling
Overallocated resources time is spread out to allow time for assigned tasks to be finished.
5. Schedule Compression - Crashing/Fast Tracking
Working with resources to get them to work in overdrive (for short durations of time).
Crashing - overdrive
Fast Tracking - starting activities early.
6. Applying leads and lags.
7. What-if scenarios.
8. MS Project <-- Project Mgmt. (Risk)
Project Costing Techniques
--------------------------
1. Expert Judgement
2. Analogous Estimation
3. Parametric Estimation
4. Bottom-up Estimation
5. Three Point Estimation
6. Cost of Quality.
7. Reserve Analysis
8. Project Mgmt Estimating Software
9. Vendor Bid Analysis.
Budgeting
---------
Difference between cost and budget
Our project cost - $330,240.00
For project starting on Jan 21st and ending on Jun 21st
Confidence in project plan -
..95% - Risk Reserve - $16,512.00
..90% - Risk Reserve - $33,024.00
..80% - Risk Reserve - $66,048.00
..70% - Risk Reserve - $99,072.00
Project Funding Limit = Project Cost + Risk Reserve.
Funding Reconciliation
Funding Schedule - Depends on requirements.
