Aim Proper planning is to control the project, to improve

the performance and to reduce the level of risks in

the development process.

Planning is important not only to take over the

control of the project, but also to produce the right

product at right time with the adequate budget.

In this research I tried to focus on Schedule

planning so that according to the schedule the tasks

can be distributed

Idea about Planningin Software

Development project For large project there are schedule planning,

quality planning, management planning,

configuration planning, integration planning

and test planning at different stage of theprocess [1].

There are 8 phases of the software (SW) life

cycle where the planning phase comes 1st [2] .

The other phases of SW lifecycle are productdesign, detailed design, code & unit test,

integration & test, implementation, operations

& maintenance and phase out.

1. Step Wise Planning[3]

At earlier stage SWP started to develop PRINCE [4]

Establish project scope & activities

y Identify stakeholders, fix method of communication

Identify standard & procedure and organisational

framework

Identify project product and activity

y What sort of product, special requirement Estimate effort for activity

Risks identify

Allocate resources & Review plan

Conventional SW planning ignores planners controlduring process Enactment stage.

To reduce the work load enactment comes in SW

1 Method applied, 1 Decision made

The decision is valid if all are Justified (drawback)

Planning and Enactment steps alternated by

y Model refining & modifying

y Initial plan specialising by applying Methods &Delegating process

y Plan adapting to the current situation

PERT applied for estimate duration

Estimated time ti= (ai+4mi+bi) / 6

y Where, ti = expected duration,ai = i-th activity optimistic time,

mi = i-th activity most likely time,

bi = i-th activity pessimistic time.

After drawing network diagram, the selected

largest path is the critical path

The tasks to be planned is combined with

precedence task and lagging task.

Analysis

The concept of PIR used as an cost effective modelfor improvement [6].

The selecting criteria for an effective plan [7] are Planning of the process,

Deliverable determination, Effort, time & cost estimation,

Resource allocation,

Managing risks, quality & the plan.

Formal & informal meeting with the developers [8],

comparing actual and predicted data at any instant

time helps in monitoring & tracking so that the

planner have the control over the plan.

Discussion

To estimate the schedule

PERT applied

GANTT chart is prepared

by listing the work activities Fig-2: Gantt chart [10]

as discrete tasks on a horizontal axis and plotting

each one against a timeline on the vertical axis [9]

Gantt chart displays tasks according to the

timeline.

Not only estimating the time, but also some other

issues such as budget, task distribution, resource

allocation came as a part of entire planning

process.
