Lesson 9

Develop the Schedule

Gantt Chart

+ easy to understand (with a lot of info)
+ easy to maintain
+ provide clear picture of current state of project
+ easy to construct

Critical Path Method 6 steps :

• define prj scope.goals and prepare work breakdown structure (WBS)
• define sequential / parallel relationships
• present network diagram with connected activities
• assign time&/cost estimates
• determine critical path with longest time through the network
• using network diagram to comitor & control project progress

CPM answer these Questions

• when whole project be finished
• which are critical / important activities to pay extra attention to
• what are non-critical activities that can afford to slack?
• is proj ahead of schedule, on schedule or behind schedule?
• are expenditures < ? > ? = ? than allocated budget?
• are there sufficient resources available to ensure timely conpletion of proj
• prj_duration - x_time ? min_cost ?

Critical Path Analysis

1. CP is longest duration path through network
2. critical path determine min time that project be done
3. there be no dely in CP activities || delay

CP Methods

1. earliest start time (est) 🏇🏼
2. earliest finish time (eft) 🏁
3. latest finish time (lft)
4. latest start time (lst)
5. duration
6. slack/float = time ( available - neceessary ) (to complete activity)

Forward Pass Rules

Backward Pass Rule

Backward Pass Rules

Calculating Float Time

Float =( LST - EST ) || (LFT - EFT)

Crashing

• shortening duration of proj => tasks--
• resources++
• time--
• cost++
• cost-- proj--
• overtime 👍

Fast Tracking

• timeline / _x => compressed => prj_dur--
• activities =

Critical Chain Scheduling

Import concepts

1. resources.exists() => true || false
2. multi-tasking
3. buffers

PERT (Program evaluation and Review Technique)

• const uncertain = true
• proj.getDuration()
