Knowledge Area 4 Project Time Management

  • Activity definition
  • Activity sequencing
  • Activity duration estimating
  • Schedule development
  • Schedule control
Activity dependency:
  • Discretionary
  • Mandatory
  • External
Precedence Diagramming Methods (PDM)
Arrow Diagramming Methods (ADM)
Conditional Diagramming Methods
  • GERT (graphical evaluation and review techniques)
  • System dynamics
Critical path method (CPM) > calculates a single, deterministic early and late start and finish date for each activity based on specified, sequential network logic and a single duration estimate.

Project evaluation and review technique (PERT)

Duration compression
  • Fast tracking
  • Crashing
Simulation - Monte Carlo analysis

Project schedule
  • Project network diagrams
  • Bar charts and GANTT charts
  • Milestone charts
PERT Value (Expected duration) = (Pessimistic + 4*(Most Likely) + Optimistic)/6
Standard Deviation (Sigma) = (Pessimistic - Optimistic)/6

EF = ES + D, LS = LF D, Float = Slack = LF - EF = LS - ES

Free Float is the amount of time an activity can be delayed without delaying the early start of an immediately following activity.

The longest path is the critical path. Slack on critical path is 0.

Heuristics, such as allocate scarce resources to the critical path first, can be applied to develop a schedule.

Schedule limitation can shape the size of project team but won't influence its organization design.

This documentation is personal study notes I prepared during my PMP certification study. The source for this study notes is partially from PMBOK 2000, PMP Exam Cram 2, and www.pmstudy.com. I only take notes on knowledge areas that I thought was useful for me. In the real exam, the contents covered are much broader and more difficult than any reference books. So I think real life experience is very important.

Crocs sandals

Suddenly one special looking sandals get popular. The brand is Crocs. It even opens a brand store at Marina Square. The design idea is from Dutch wooden shoes, I guess. A pair of Crocs sandals is sold at around SGD 50. The price is justified for what it is made of - Croslite. Based on Crocs website, "Croslite™, a proprietary Closed Cell Resin (PCCR) which is NOT plastic NOR rubber. Croslite™ is closed-cell in nature and anti-microbial, which virtually eliminates odor. it is an extraordinary impact absorbing resin material developed for maximum cushioning. its closed cell properties resist odor, inhibits bacterial and fungal growth and are non toxic. this versatile material can be worn next to skin and be cleaned with just soap and water." However, it really looks like made of plastic or rubber, and the design is unique. Replica comes. they are sold at SGD 20, SGD 10, SGD 5 depending on quality.

Singapore Girl Sex Clip Posted Online

A couple days ago, a sex video clip about a female Chinese graduate student Wang Ting Ting (王婷婷) was posted on the internet. Just as it is about to cool down, another sex video clip pops. It is a sex clip of a Singapore Nanyang Polytechnic student . The video clip was stored on her cell phone. Someone stole it and posted the video clip on the Internet. This is a breaking news. It is even reported on major Singapore and Malaysia newspapers. Now we have so many cool gadgets. It is a breeze to shoot photos/videos, and share them on the internet. Everyone, even dog, is on the internet waiting for breaking news. Be careful when you do something secret or stupid. It may appear all over the world, live!

No smoking sign

Watch out this sign before you light the cigarette up. SGD 1000 fine! However, I wonder if someone had really paid so much for violation.

Prostitutes in Singapore

Singapore is very realistic about this issue. Prostitution is legal. The famous red light zone is Geylang area. I heard Hong Kong officials are considering to legalize this business in HK also. Singaporeans are not allow to work as prostitute. Maybe also SPR. The prostitutes are mainly foreign workers from poor countries in SEA area, such as Indonesia, Thailand, India, Malaysia, not from China. They come under special 2-year working pass, and must pass the health exam, yes, to prevent STD such as HIV, AIDS and so on. The brothels are mixed with normal resident houses. The brothel's house number is red lighted. The price is ranged from SGD 50 to SGD 200. Illegal sex workers are also around, and in some massage clinics. A very recent fatal case and newly effective government policy make a special social group - Chinese accompanying mom for studying kids a hot media buzz again.
