Project Schedule Management (2) Flashcards
What are the 6 processes in the project schedule management knowledge area?
Plan schedule management, define activities, sequence activities, estimate activity durations, develop schedule, control schedule
What are the inputs for the plan schedule management process?
Scope MP, project charter, EEFs (culture, resource availability, schedule software, tailoring processes, commercial databases), OPAs (lessons learned, existing schedule guidelines, template, reporting tools)
What are the tools used for the plan schedule management process?
Meetings, expert judgement, data analysis (alternative)
What are the outputs of the plan schedule management process?
Schedule MP
What are the inputs of the define activities process?
PMP (schedule MP, scope baseline), EEFs (culture, commercial databases, PMIS), OPAs (lessons learned, standard processes, templates)
What is a PMIS?
Project management information system
What are the tools used for the define activities process?
Expert judgement, meetings, rolling wave planning, decomposition
What are the outputs of the define activities process?
Activity list, activity attributes, milestone list, change requests, PMP updates (schedule and cost baselines)
What is progressive elaboration?
Iterative process of increasing level of detail in a PMP as more info is available
What is rolling wave planning?
Iterative process - work due soon is planned in detail and work in the future is planned at a higher level
What are the inputs of the sequence activities process?
PMP (schedule MP, scope baseline), project documents (activity attributes, activity list, assumptions, milestone list), EEFs (standards, PMIS, scheduling tools), OPAs (policies, templates, lessons learned)
What are the tools used for the sequence activities process?
PMIS (e.g., Microscoft project), precedence diagramming method, dependency determination and integration, leads and lags
What is the precedence diagramming method?
Schedule model - activities are nodes and graphically linked by logical relationship to show sequence (gantt with FS, FF, SS, SF)
What are mandatory dependencies?
Legally inherent to do work - e.g., cannot start building walls until foundation is down
What are discretionary dependencies?
Preferred logic - e.g., best to install electricity after plumbing
What are external dependencies?
Relationship of project with external activities usually outside of project team’s control - e.g., waiting for part to arrive from external vendor
What are internal dependencies?
Inside project team’s control
What is a lead?
Amount of time a successor activity can be advances (e.g., landscaping could start 2 weeks before punch list completion F-S)
What is a lag?
Amount of time a successor activity will be delayed with respect to predecessor activity (e.g., team may begin editing draft 15 days after the begin writing it start-start)
What are the outputs for the sequence activities process?
Project document updates (activity attributes, activity list, assumption log, milestone list), project schedule network diagrams
What are the inputs for the estimate activity durations process?
OPAs (historical duration info, project calendar, estimating policies, scheduling methods, lessons learned), EEFs (reference data, commercial info, location of team), PMP (schedule MP and scope baseline), project documents (activity attributes, activity list, assumptions, lessons learned, milestone list, project team assignments, RBS, calendars, requirements, risk register)
What are the tools used for the estimate activity durations process?
Analogous estimating, bottom up estimating, three point estimating, parametric estimating, expert judgement, data analysis (alternative and reserve/contingency), decision marking, meetings
What are the outputs of the estimate activity durations process?
Duration estimates, project document updates (activity attributes, assumptions, lessons learned), basis of estimates
What is analogous estimating?
Uses past data from similar activity to estimate (used when there is limited amount of detailed info about project available)
What is parametric estimating?
Uses statistical relationship between historical data and other variables to calculate an estimate for activity parameters
What is 3 point estimating?
= optimistic time + most likely time + pessimistic time divided by 3
What is bottom up estimating?
Summing estimates of granular activities
What are the inputs for the develop schedule process?
OPAs (scheduling methodology, project calendars), PMP (schedule MP, scope baseline), project docs (activity attributes, activity list, assumptions, basis of estimates, duration estimates, lessons learned, milestone list, project schedule network diagrams, project team assignments, resource calendars, resource requirements, risks), EEFs (standards, communication channels), agreements
What are the tools used for the develop schedule process?
PMIS, leads and lags, critical path method, resource optimization (leveling and smoothing), schedule compression (crashing and fast tracking), schedule network analysis, agile release planning (release plan and iteration plan), data analysis (what if and simulations)
What are the outputs of the develop schedule process?
Project doc updates (activity attributes, assumptions, duration estimates, lessons learned, resource requirements, risks), schedule data, schedule baseline, project calendars, project schedule (bar/gantt charts, milestone charts, or project schedule network diagrams), PMP updates (schedule MP, cost baseline), change requests
What are project schedule network diagrams?
Activity date information showing network logic and critical path (logical relationships of predecessors and successors)
What is the critical path method?
Estimates minimum project duration and determines amount of schedule flexibility on logical paths within model. Zero total float
example: longest path is A, C, D so that is critical path
What are resource optimization techniques?
Resource leveling and resource smoothing
What is fast tracking?
Method of schedule compression where performing a portion of duration activities in parallel that are normally done in sequence may result in increased risk
What things need to be calculated for critical path method?
Early start, early finish, late start, late finish, free float and duration
What is a forward pass in critical path method?
Calculate early state and early finish dates for each activity
What is a forward pass in critical path method?
Calculate early state and early finish dates for each activity
What is a backward pass in critical path method?
Calculate float with critical path having no float. Drop the last early finish date into the late finish slot and go backwards
What is a backward pass in critical path method?
Calculate float with critical path having no float. Drop the last early finish date into the late finish slot and go backwards. Do late finish - early finish to calculate float
What is resource leveling?
Used when there are limits on available resources and it may affect schedule/critical path
What is schedule compression?
Used to shorten schedule without reducing scope to meet constraints or other objectives (crashing or fast tracking)
What is crashing?
Schedule compression technique that shortens schedule duration by adding resources
What is resource smoothing?
Activities may be adjusted but only within float (doesn’t affect critical path)
What is agile release planning?
High-level summary timeline of release schedule (3-6 months). Release of different iterations (release plan made up of iteration plans)
What are the inputs for control schedule?
PMP (schedule MP, schedule baseline, scope baseline, performance measurement baseline), project docs (lessons learned, project calendars, schedule, resource calendars, schedule data), work performance data, OPAs
What are the tools used for control schedule?
Data analysis (earned value, iteration burndown, performance reviews, trend analysis, variance analysis, what-if), critical path method, PMIS, leads and lags, schedule compression
What is an agile approach for control schedule?
Reprioritize remaining project work
What is an iteration burndown chart?
Tracks work that remains in iteration backlog
What are the outputs for control schedule?
Work performance information, schedule forecasts, change requests, PMP updates (schedule MP, schedule baseline, cost baseline, performance measurement baseline), project doc updates (assumptions, basis of estimates, lessons learned, project schedule, resources calendar, risks, schedule data)
