What is Project Management ?
Project management is the discipline of planning,
organizing, securing, managing, leading, and controlling
resources to achieve specific goals. A project is a
temporary endeavor with a defined beginning and
end ,undertaken to meet unique goals and objectives. It is
a systematic approach to planning and guiding project
processes from start to finish
Five Stages: Initiation, Planning, Executing,
Controlling, and Closing.
Planning in Project ManagementProject planning is a discipline for stating how to
complete a project within a certain timeframe, usually
with defined stages, and with designated resources. One
view of project planning divides the activity into:
Setting objectives (these should be measurable)
Identifying deliverables
Planning the schedule
Making supporting plans
Supporting plans may include those related to human
resources, communication methods, and risk management.
Planning in Software Projects
Software project management begins with a set of
activities that are collectively called project planning. Before
the project can begin, the Project Manager and the
software team must estimate and look into.
The work to be done
The resources that will be required
And the time that will elapse from start to finish.
The future and accept some degree of uncertainty as
matter of course.
Lack of Planning leads to
…It is often said that early planning is impossible
because precise information concerning the project goals,
customer needs and system constraints is not available at
the beginning of a software project. But a major purpose of
the planning phase is to clarify goals and needs required
to plan a software project. Lack of good planning leads to
Schedule slippage
Cost overruns
Poor quality
High maintenance cost.
Software Project Planning Activities1.Define the Problem,
2.Develop Solution Strategy,
3.Planning the Development Process.
I. Define the Problem Involves :-
Understanding the problem
Justifying the need of a Software
Identifying the functions of a major subsystem
Identify the goals and requirements
Establishing high- level acceptance criteria for the
system.
II. Developing Solution Strategy involves:-
Outlining several solution strategies
Conducting feasibility study for each strategy
Recommending a solution strategy, indicating why
other strategies were rejected.
Developing a list of priorities for product
characteristics.
III. Planning the Development Process involves:-
Defining a life Cycle model and an organizational
structure of the project.
Planning the configuration management, quality
assurance and validation activities.
Determining phase development tools, techniques
and notation to be used.
III. Estimation in Planning Phase include:-
Preliminary cost estimation for system development
•Expert judgment
•Work breakdown structure
•Algorithmic cost model.
Preliminary staffing estimates
Computing resources required to operate and maintain the
system.
Identifying the sources of information and refer to them throughout
the project plan.
Software measures for quality and product
•Metrics used – Size oriented and function oriented
•Function point metrics for function point analysis.
Journal 1 ( IEEE) - Successful software projects need requirements planning
by Annie I Anton, Professor, College of Eng. North Carolina State University
This paper mainly focus on importance of understanding the requirements.According to this author top three project challenged factors are:1. Lack of user involvement 2.Incomplete requirement and specification3.Changing requirements and specifications Standish Group surveyed that bad requirement causes 40 – 60% software failures
Key Principles can help eliminate defects during requirement planning.
1.Understanding the problem before expressing the requirement.
2. Involve the stake holders early on and sustain their involvement to validate
requirements. We must give customers repeated opportunities to validate
requirement.
Prototypes – give users a tangible product – it helps to interact
Journal I ( IEEE) - Successful software projects need requirements planning

3. Ensure that Critical Requirements are considered. Scenario Analysis – Obstacle analysis – What if questions
4.Give non-functional and quality requirements as much attention as functional
requirements.-users emphasis on functional requirements.
Non functional requirements express a software system’s properties,
including security, reliability, portability, and robustness.
Good requirement planning mean software can be cheaper to produce,
easier to build and less prone to unexpected failures.
Journal 2( IEEE) - Software project initiation and planning - an empirical study
by D.Greer-UK & R.Conradi- NorwayThis paper describes the study on 14 established Norwegian software companies - How they initiate and pre-plan software development projects.
The aim was to obtain an indication of the range of planning activities carried out be these 14 software firm.
The Instrument of study was structured interviews. (Questions are left completely open ended )- Sampling convenience sampling of 31 companies.CMM level integration (Capability Maturity Model ) approach emphasis the role of through planning in the software projects for improving the predictability and to ensure the process improvement.Question included from the topics :
Software process Choice
Feasibility Study
Early Planning Documents
Release Planning
Risk Management
Journal 2( IEEE) - Software project initiation and planning - an empirical study
by D.Greer-UK & R.Conradi- NorwayFindings of the Study
1. Most of the firms using Agile method (IID), few of them using Water fall model
2.Study confirms the perceived importance of Feasibility Study , but firms mainly
focus on Economical feasibility ,although several did mention on technical
feasibility.3.Most companies produce at least a partial requirements documents. Early cost, schedule and budgets are often documented, but other data on decision taken are not documented.
4.Waterfall process associated with a single release do often include provision for
future releases. For agile scrum projects , the number of releases planned is
always two or more.
5.Risk Identification and Risk Monitoring are common activities but other risk
management were not explicitly performed in most of the companies.
Conclusion …..The early planning of software project is
very vital and the software project planner must estimate three things before a project begins: How long it will take
How much effort will be requiredHow many people will be involvedIn addition , the project planner must
predict the resources ( Hardware and Software ) that will be required and the risk associated with this project.
The Success of software project relay on user involvement and their participation
