2. Technical Development of software
• What is software?
• Computer programs and associated documentation together constitute
the software .
• A software may be developed for :
1. A Single customer according to his/her specification (bespoke)
2. General market
i.e generic in nature and to be sold to a range of different customers through
different channels.

3. What are the characteristics of good
software ?
1.Maintainability:
Software must evolve to meet changing needs.
2. Dependability:
Software must be reliable
3.Efficiency:
Software should not waste system resources.
4. Usability
It should be usable by the users for whom it is
designed.

4. Programs vs Software Products
Characteristics Program SW product
Users self Others
Number of user Self/few Large number
Size small Large
Functionality limited Large
Interfaces Ok Well designed
Environment One Several
System Used by itself Works with other
systems
User background Similar Varied
Presence of bugs Not a major concern Major concern
Documentation Minimal Exhaustive
Testing Minimal Exhaustive
Cost/user High low
Developers One /few Many
Use of standards, etc Not essential essential

7. Trends in ERP solutions
• ERP SOFTWARE has embarked beyond the
traditional business processes to support all
business decisions.
• IT/IS planners are considering applications
that include ERP:
• Existing ERP software is also playing a role in
such decisions.

8. Trends IN ERP
• Organizations stay with their ERP vendor (SAP,
ORACLE etc) rather than looking elsewhere for
additional solutions e.g data warehousing, data
mining.
• Trend2: several software vendors are building
applications that integrate with the well known
ERP software packages.
trnd3: successful deployers of erp , offer
consultancy service to other prospective
deployers.

9. Software Maintenance
• Software maintenance consumes more than
60% of the software budgets and it is growing.
• Mechanism needs to be developed for
evaluating, controlling and making
modifications.
• Cycle of software reengineering activities
during maintenance:
• Inventory analysis of software assets , Document restructuring, Reverse engineering, code
restructuring, data restructuring, Forward engineering.

10. Maintenance model for major rework

11. Evolving role of software
• Software delivers the most important product
of our time: information

12. Evolution of Software engineering
Discipline
• SE evolved over the last 50/60 years with
contributions from software professionals and
several researchers from different discipline
• Systematic and engineering like approach to
software development .

13. Software engineering definitions
• IEEE: systematic approach to development,
operations , maintenance , and retirement of
software.

14. System development cycle:
