This document discusses changes in software engineering, including shorter time to market, use of object-oriented applications, user desktop computing, graphical user interfaces, increased networking, open source platforms, newer development models, and economic factors. It provides examples of how each change has impacted software engineering processes and timelines. Topic exercises are included for each change discussed to help students apply concepts.

3. PART 1 CONT’D
i. Time to Market:
This described the time taken to conceive a project
idea, transform the idea to a systemic form and
deliver the project.
This change is enhanced with modern techniques
of reviewing and testing software.
Also, the advent of memory technology has jettison
the need for rigorous and time-wasting code
optimizing process.

4. PART 1 CONT’D
i. Discuss strategies/ways by which your
application can beat other competitors to the
market.

5. PART 1 CONT’D
ii. Object Oriented App:
With the birth of object-oriented
software, developers now have access to
rich library and reusable
artifacts/components, which in a great
measure reduces time taken for their app
to land in market.
The CHANGE in SOFTWARE ENGINEERING

6. PART 1 CONT’D
i. Pick any choice object-oriented
language and discuss its features as
well as its shortcoming as a language.
ii. As notable in the previous slide, OO
contributes largely in terms of library
repository. Demonstrate the use of
library resources in the OO language
selected in (i).

7. PART 1 CONT’D
iii. User Desktop Computing
With the proliferations of different
desktop applications/software, software
developers can now concentrate on
building sophisticated and more complex
applications as users can on their own
develop simple, common and domestic
applications with the various freely
available desktop apps.
The CHANGE in SOFTWARE ENGINEERING

8. PART 1 CONT’D
i. Decide on any desktop app and
develop a simple but sensible app.
ii. Document every step of the app’s
design and execution/implementation
flow to prove originality of authorship

iv. GUI
Gone are those days when DOS-based
apps when reigning. Now, the table has
turned, windows-based apps are on the
streets. This has greatly enhanced the
embracement of software and has
resulted into higher yields for
practitioners.
The CHANGE in SOFTWARE ENGINEERING

10. PART 1 CONT’D
i. Many event-driven and graphical
programming languages exist.
Demonstrate the advantage of
creating a user-friendly and easy
navigation in app, using such
language.
UTE IV

11. PART 1 CONT’D
v. Networking
With the advent of internet and rapid
increase in the level of networking across
organizations, users have no ‘headache’
of feedbacking the developer on every
simple ‘problem/challenge’ encountered
as enquiries can be made online to trace
the problem and access info for probable
solution.
The CHANGE in SOFTWARE ENGINEERING

12. PART 1 CONT’D
i. Develop a simple ‘Online
Troubleshooting App’ for feedbacking
clients on program error such as
‘library not found….’.
UTE V

13. PART 1 CONT’D
vi. Open Source
Aside offering resources in terms of
library, solution etc., open source
platform also affords enhancement to
solution by giving rooms for other
authors/developers to contribute to the
efficiency and robustness of apps.
The CHANGE in SOFTWARE ENGINEERING
13

14. PART 1 CONT’D
i. Access any open source platform,
modify any available educational
software to suit your taste.
ii. Report and document the accessed
platform as well as the functional app,
library or codes accessed, as the case
may be.
UTE VI

15. PART 1 CONT’D
vii. Economics
A technology-driven society enhances the
acceptance of software application. The
witnessed rampant usage of mobile
technology has also led to high rate of
mobile app development.
The CHANGE in SOFTWARE ENGINEERING
15

16. PART 1 CONT’D
i. Bring up a short term paper titled:
‘Analyzing the impact of technology
on software evolution and
embracement’.
ii. Develop a mobile demo app, capable
of catching the attention of a novice
or new comers to this field of
computing.

viii. Newer and Faster Development
Models
No doubt, Water Fall Model presents lots
of advantages over Evolutionary Model.
Howbeit some of the major setbacks in
the models include time to market and
lack of adequate validation process. This
has however given birth to new and faster
software development model including
modified waterfall model with
appropriate validations.
The CHANGE in SOFTWARE ENGINEERING

18. PART 1 CONT’D
i. Criticize the Waterfall Model.
