Define activity
process of identify and
document specific action
How?
Decompasition to
one person
Detemine milestones and deliverable
Define activities needed to produce deliverable
Describle activity detail

Sequence Activities
How?
1.Determine dependencies between activities
Internal dependencies
External dependencies
Madatory dependencies
phụ thuộc bắt buộc
Discretionary dependencies
phụ thuộc tùy ý
2. Sequence activities using appropriate diagram
have 4 logical relationships
PS
(Finnish-to-start)
FF
(finnish to finish)
SS
(start to start)
SF
(start to finnish)
3.Applying leads and lags(if necessary)
Lead
Start prior
(khoảng thời gian activity có thể bắt đầu
trước khi activity trước kết thúc)
Lag
Waiting time
Output

Estimate Activity Duration
How?
tool and techniques
Analogous Estimating
(Top-down)
less costly and time but less accurate(chính xác)
Parametric Estimating
(sử dụng công thức)
uses a statistical relationship
Bottom-up Estimating
implement with team and asign to one person
PERT - Three point estimate
P
(pessimistic - bi quan)
O
(optimistic - lạc quan)
M
(most likely - trung bình)
Triangular distribution: E = (P + M + O) / 3
Beta distribution: E = (P + 4M + O) / 6
Reserve Analysis - time reserves
thời gian dự phòng
Alternatives analysis

Develop schedule
How?
Find critical path
không có float
Resource optimization
tối ưu hóa tài nguyên
Schedule compression
compare with milestones
Schedule reserves
kế hoạch dự phòng time - delay
Baseline has been approved
Techniques
Schedule Network Analysis
– Critical path method
– Resource optimization
– Modeling (What-if analysis)
Critical Path Method (CPM)
the longest duration,
Float(total float)
độ trễ của activity mà không làm trì hoãn ngày kết thúc
float với project
Free Float
Free Float = ES of next activity – EF of predecessor - 1
độ trễ của activity mà không ảnh hướng đến start của activity tiếp theo (2 preactivity to 1 activity)
Project Float
thời gian project có thể trễ mà không ảnh hưởng đến ngày bàn giao với khách hàng - so với deadline của customer
Resource Optimization
Resource leveling
to balance demand for resources
=> tận dụng nguồn lực làm dàn trải theo thời gian và sẽ gây ra trễ deadline (Project’s critical path is changed)
Resource smoothing
sử dụng tối đa nguồn lực có thể phải OT để hoàn thành đúng thời gian bàn giao
Schedule Compression
Crashing
Add more resource => increased cost
Fast Tracking
– Critical activities to be done in parallel or
with some overlap. (làm song song hoặc làm trước khi activity trước hoàn thành)
=> increases risk
Output

Control schedule
How?
Monitoring status and knowing the actual performance
to date.
Updating the schedule model
Compare the actual start and finish
dates to the approved baseline
Manage change to the schedule
