PART 1 CONT’D The CHANGE in SOFTWARE ENGINEERING 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. 3

PART 1 CONT’D

Under Topic Exercise (UTE) I i. Discuss strategies/ways by which your application can beat other competitors to the market.

4

PART 1 CONT’D The CHANGE in SOFTWARE ENGINEERING

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.

5

PART 1 CONT’D UTE II

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). 6


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. 7

PART 1 CONT’D UTE III

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

8


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. 9

PART 1 CONT’D UTE IV

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.

10


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. 11

PART 1 CONT’D UTE V

i. Develop a simple ‘Online Troubleshooting App’ for feedbacking clients on program error such as ‘library not found….’.

12


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. 13

PART 1 CONT’D UTE VI

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. 14


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.

15

PART 1 CONT’D UTE VII

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.

16


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. 17

PART 1 CONT’D UTE VIII

i. Criticize the Waterfall Model.
