Interdependencies between tasks
|
Terms
Work Schedule
Assignment of work on the time basis.
Network
Logical presentation (i.e. showing the sequence) of pending tasks.
Task/Activity
An action which is aimed at achieving of a given objective (it has to
be connected with a specific final product); each task has a defined point
of start and completion (Start/Completion) and each task consumes time and
other resources; tasks have their preceding and following tasks.
Event
The moment of task commencement or completion,
Milestone: An event which does not consume resources.
Critical Path
Continuous set of events, from the very beginning to the end of
dependence grid, with the longest delivery time.
The Critical Path determines length of project delivery time.

Project delivery process
The project delivery process is a set of various activities (work)

Work structure
Levels of detail

Work structure description rules
- Each activity in the structure should be linked to a specific
end-product
- Each activity should be assigned to a specified person or team (responsibilities)
- Completion of work assigned to a given activity should be verifiable
- An activity can consists of various subtasks which have their own
work structure (hierarchy)
|
Rules of work structure break-down
- End-products
- Functions
- Delivery time
- Scope of work
- Place of delivery
- Delivery team
- ...
|
Work structure constitutes a basis for:
- Planning and cost estimates
- Defining scope of work
- Defining paths for development and review points
- Assignment of responsibilities
- Identification of risk
- Implementation of changes
|
Project delivery planning techniques
- Gantt charts
- Milestone charts
- Network analysis methods (PM, PERT)
|
Network methods (CPM, PERT)
CPM – Critical Path Method
PERT – Program Evaluation and Review Technique
- Setting the plan of action (complete list of tasks)
- Setting task interdependencies (preceding, following and "empty"
tasks)
|
Each task needs:
- Task description
- Personal responsibility
- Time lapse estimate
- Planning project duration
- Task starting date (the earliest possible date/the latest acceptable
date)
- Task ending date (see above)
|
|
To each task following date milestones pertain:
Task commencement
- NWP – the earliest possible date
- NPP – the latest acceptable date
Task completion
- NWK – the earliest possible date
- NPK – the latest acceptable date
