“Project” A planned activity A Specific plan or design A planned undertaking

“Management” Setting objectives for a system

and monitoring the performance of the system

5

Introduction The key idea of “Software project

Management” is Planning, Monitoring and Control of software projects

A Software project must satisfy real needs

In order to meet this needs project stakeholders and their objectives must be identified

6

Importance of SPM A survey in USA, 2003 published that

82% of project were late 43% exceeded their budget

Reason is management of project Lack of skills and proven approach to

project management and risk management

What is a Project? A dictionary definition: “ A Planned

Activity” i. e. How to carryout a task before

starting. “Planning”: Thinking Carefully about

something before doing it. Other activities of planning are routine

maintenance performed so many times, and documented – helps newcomers.

8

Characteristics of projects are: Non-routine tasks are involved Planning is required Specific objectives are to be met The project has a predetermined time

span Work is carried out in several phases The resources are constrained The project is large or complex.

Software Project VS Other Projects

Fred Brooks identified some characteristics of software projects which makes it difficult are Invisibility Complexity Conformity Flexibility

10

Activities of SPMFeasibility Study

Plan

Project Execution

Is it worth doing?

How do we do it?

Do it!!

11

The Feasibility Study: Assesses whether a project is worth starting

Planning: Outline plan for the whole project and a detailed one

for the first stage Project Execution:

The execution of the project often contains design and implementation sub-phases.

12

Software Development Activities- ISO 12207

Requirement Analysis Architecture Design Detailed Design Code and Test Integration Qualification Testing Installation Acceptance Support

13

Plans, Methods and Methodologies A plan for an activity must be based on some idea of a

method of a work. Analyze the requirements for the software Devise and write test cases Create test scripts Compare the actual results and the expected results

A Method relates to a type of activity in general, a plan that takes that method and converts it to real activities

Its start and end dates who will carry out What tools and materials

The output from one method might be the input to another. Group of methods or techniques are often grouped into methodologies such as object-oriented design

14

Some ways of categorizing Software Projects

Compulsory Versus Voluntary users Eg. Moodle – Games,Google

Information systems versus embedded systems Eg. Stock Information – Air Conditioning Equipment

Outsourced projects Giving some parts of its work to other companies

Objective- driven development Identifying the need for a new software system

15

Stakeholders These are people who have a stake or

interest in the project. Stakeholders can be categorized as:

Internal to the project team External to the project team but within the

same organization External to both the project team and the

organization

16

Setting Objectives Stakeholders are those who actually own

the project. They control the financing of the project. They set the objectives of the project. The objectives should define what the

project team must achieve for project success.

17

Sub-Objectives and Goals A more appropriate goal or sub-objective

for the software developers is to keep development costs within a certain budget.

SMART: Specific Measurable Achievable Relevant Time Constrained

18

Business case Development costs should not be

increased Features of the system should not be

reduced Delivery date of the project should

not be delayed

19

Project Success and Failure Success:

Preserving the business case Failure:

Stakeholders have different interests
