5. EXAMPLE
Operations and maintenance
Find other requirements Correct and maintain control
implementation and conversion
Make a pilot test Use it in real life scenario
Physical design
formulate how to input Make the worksheet
Conceptual design
Accounting knowledge Excel or accounting software
System Analysis
Accounts receivable sheet Inventory system

6. PLANNING SYSTEM DEVELOPMENT
Master plan
Project
development
plan

7. PLANNING TECHNIQUES
 PERT( Program evaluation and review technique)
 Gantt chart

8. BEHAVIORAL ASPECTS OF CHANGE
Positive and negative ways of people’s reaction to
change, minimizing these behavioral reactions is
crucial for successfully implementing a new system.

9. HOW BEHAVIORAL PROBLEM OCCURS
To minimize adverse behavioral reactions, one must
know why resistance takes place. Some important
factors are given below:
Fear
Top
Management
support
Experience with
prior changes
Communication
Disruptive
nature of change
Emotion and
Bias
Personal
characteristics
And background

10. FORMS OF RESISTANCE
Resistance takes one of three forms:
Aggression Projection Avoidance

11. PREVENTING BEHAVIORAL PROBLEMS
Obtain
management
support
Meet user
needs
Involve users
Allay fears, and
stress new
opportunities
Avoid
emotionalism
Provide training
Reexamine
performance
evaluation
Keep
communication
lines open
Test the system
Keep the
system simple,
and humanize it
Control users’
expectations

12. FEASIBILITY ANALYSIS
An investigation to determine whether it is practical to
develop a new application or system

13. ASPECTS OF FEASIBILITY ANALYSIS
Feasibility
analysis
Economic

16. SYSTEM ANALYSIS

17. STEPS OF SYSTEM ANALYSIS
Initial Investigation System Survey Feasibility Study
Information needs and
system requirements System Analysis report

18. THANK YOU

19. SYSTEM SURVEY
 Objectives of system survey
 Understanding company operation
 Assessment of current and future process
 Develop working relationships
 Collect data

20. METHODS OF COLLECTING DATA
 Interview
 Questionnaire
 Observation
 System documentation

21. STRATEGIES TO DETERMINE AIS
REQUIREMENTS
 Ask users what they need
 Analysis external system
 Examine existing system
 Create a prototype
