Chapter 6: Project Schedule Management Flashcards
PERT
Program Evaluation and Review Technique (O + (4*ML) + P)/6 AKA Beta Distribution O = Optimistic Estimate ML = Most Likely P = Pessimistic
Three-point Estimate
An estimating technique for each activity that requires optimistic, most likely, and pessimistic estimates to be created. Based on these three estimates, an average can be created to predict how long the activity should take. AKA Triangular Distribution Find the average of 1. Optimistic = O 2. Most Likely = ML 3. Pessimistic = P
(O + ML + P)/3
Forward Pass (Network Diagram)
ES + Du - 1 = EF
ES = Early start (which day are you starting)
Du = Duration of the work
EF = Early Finish ( When will you finish the work)
Backward Pass (Network Diagram)
LF - Du + 1 = LS
LS = Late start (which day are you starting)
Du = Duration of the work
LF = Late Finish ( When will you finish the work)
FLOAT
LF - EF or LS - ES
LF = Late Finish ( When will you finish the work)
EF = Early Finish ( When will you finish the work)
LS = Late start (which day are you starting)
ES = Early start (which day are you starting)
Activity List
The primary out of breaking down the WBS work packages
Project Schedule Management Processes
Planning: 1. Plan Schedule Management 2. Define Activities 3. Sequence Activities 4. Estimate Activity Durations 5. Develop Schedule Monitoring and Controlling 6. Control Schedule
Plan Schedule Management
It is a process of establishing the policies, procedures and documentation for planning, developing, managing, executing and controlling the project schedule
Time-boxed periods
These are durations during which the team works steadily toward completion of a goal.
It helps to minimize scope creep as it forces the teams to process essential features first then other features when time permits
Level of accuracy
It specifies the acceptable range used in determining realistic activity duration estimates and may include an amount for contingencies
Define activities
The process of identifying and documenting the specific actions to be performed to produce the project deliverables
Rolling Wave Planning
It is an iterative technique in which the work to be accomplished in the near term is planned in detail, while work further in the future is planned at a higher level
- Form of progressive elaboration
- applicable on work packages, planning packages and release planning when using an agile or waterfall approach
Activity Attributes
They extend the description of the activity by identifying multiple components associated with each activity
Milestones List
It identifies all project milestones and indicates whether the milestone is mandatory, such as those required by contract or optional such as those based on historical information
Sequence Activities
It is the process of identifying and documenting relations among project activities
Project Schedule Network Diagram
It is a graphical representation of logical relationships as referred to as dependencies among the project schedule activities
Estimate Activity Durations
It is the process of estimating the number of work periods needed to complete individual activities with estimated resources
Reserve Analysis
It is used to determine the amount of contingency and management reserve needed for the project
Cost reserves are for unknown unknowns within a project. The management reserve is not part of the project cost baseline, but is included as part of the project budget.
Contingency Reserve
They are the estimated duration within the schedule baseline, which is allocated for identified risks that are accepted
Management Reserve (COST)
Specified amount of project budget withheld for management control purposes and are reserved for unforeseen work that is within scope of the project
Duration Estimates
They are quantitative assessments of the likely number of time periods that are required to complete an activity, a phase or a project
Develop Schedule
It is the process of analyzing activity sequences, durations, resource requirements and schedule constraints to create a schedule model for project execution and monitoring and controlling
Schedule Network Analysis
It is the overarching technique used to generate the project schedule model. Employs 1. critical path method 2. Resource optimization techniques 3. Modelling techniques
Critical Path Method
Used to estimate the minimum project duration and determine the amount of schedule flexibility on logical network paths within the schedule model
Resource Optimization
It is used to adjust the start and finish dates of activities to adjust planned resource use to be equal to or less than resource availability
Resource Smoothing
A technique that adjusts the activities of a schedule model such that the requirements for resources on the project do not exceed certain predefined resource limits
What-if Analysis
It is a process of evaluating scenarios in order to predict their effect, positive or negative on project objectives
Simulations
It models the combined effects of individual project risks and other sources of uncertainty to evaluate their potential impact on achieving project objectives
Most common technique: Monte Carlo Analysis
Leads and Lags
They are refinements applied during network analysis to develop a viable schedule by adjusting the start time of the successor activities
Schedule Compression
These are techniques used to shorten or accelerate the schedule duration without reducing the project scope in order to meet schedule constraints, imposed dates, or other schedule objectives
Agile Release Planning
Provides a high-level summary timeline of the release schedule based on the product roadmap and the product vision for the product’s evolution
- also determines the number of iterations or sprints in the release
