Question 1

what is a GANTT chart?

Answer 1

provides a visual of what needs to be done and when. excellent for tracking schedules because you can see interdependencies between tasks. NOT EFFECTIVE WHEN THERE IS A HIGH NUMBER OF ACTIVITIES.

Question 2

what are the 4 types of relations/ interdependencies?

Answer 2

FS: one task must finish before another can start, most common
SS: several tasks can begin simultaneously
FF: a task cannot end until the previous one is completed
SF: least common task relationship, one task cannot end until another has started (shift work)

Question 3

benefits of GANTT

Answer 3

break down a project in to manageable tasks
easily view dependencies and relationships
visualize and monitor the progress of tasks over time
identify a critical path

Question 4

what is critical path analysis (CPA)?

Answer 4

used to identify activities on a critical path. breaks a project into tasks, displays them in a flow chart, and then calculates the project duration based on estimated time frames.

Question 5

advantages of CPA

Answer 5

identifies most important tasks
reduces timelines
compares planned progress and actual progress

Question 6

disadvantages of CPA

Answer 6

reliability is based on accurate estimates and assumptions
does not guarantee success of a project
resources may not be as flexible as planned

Question 7

what is a PERT chart?

Answer 7

Program Evaluation and Review Technique
they map the project roadmap ahead. graphical representation of a project’s timeline, tasks, and the dependencies between those tasks.

Question 8

when should you use a PERT chart?

Answer 8

when your project has simultaneously moving parts
when you’re conducting a feasibility study

Question 9

what is the formula for the estimated expected duration of a project?

Answer 9

E = (O + 4M + P) / 6
E= estimated expected time O= optimistic time P= pessimistic time M= most likely time
