Unit 6 Research Paper 1: “Advantages and Disadvantages of Using Case Structures”
Advantages:
Because of their many important advantages and extreme popularity, use cases have become a fundamental part of object technology and have been incorporated in one form or another into most major object-oriented development methods.
1.You can create logic flows; in which is a method used to make the reading easier for the reader.
2.Because they are written in natural language, use cases are easy to understand and provide an excellent way for communicating with customers and users. 3.Static depth, in which “if” can be set to however amount the user wants.
4.Low CPU overhead.
5.You can insert certain captions using “< >//”
6.As a user-centered technique, use cases help ensure that the correct system is developed by capturing the requirements from the user's point of view.

-------------------------------------------------

Disadvantages:
In the rush to jump onto the use case bandwagon, use cases have been perceived by some as either a panacea or as an end in-and-of themselves. Unfortunately, this has often led to the uncritical acceptance of use cases without any examination of their numerous limitations and ample opportunities they offer for misuse. The following provides an overview of the major risks associated with use cases:
1.If it is case specific, in which a case can’t be re-used.
2.If it is static, in which the user will not be able to create most implements. 3.The “Bloated syntax” takes space, in which case is more functional when used in an equation. 4.It takes a lot of maintenance, because for any change requires fixing throughout the entire structure. 5.Most programmers use it; which means that whatever you’re creating is basically of the norm. 6.Use cases are not object-oriented 7.This scattering of objects to use cases leads to the Humpty Dumpty effect, in which all the kings designers and all the king's coders are unlikely to put the objects and classes back together again without a massive expenditure of time and effort.
8.The simple structure of the use case model does not clearly map to the network structure of the object model with its collaborating objects and classes.

It will concentrate on strategy development and competitive advantage. It is consciously designed to highlight the significant emerging trends in strategic management. The course provides students with a practical approach to the formulation and implementation of corporate, business, and functional strategies. The course is also meant to give graduate students the skill to derive strategies rationally for the organizations that they are currently working for or have chosen for their analysis. There are no strategic decisions that are perfect under the current turbulent business environment. Therefore, a rational approach to strategic decision-making is deemed most appropriate. However, the strategy developed may not survive in its original form upon execution. Accordingly, these strategies have to be adjusted to meet the current challenges. Emergent strategies that were unplanned would also need to be exploited for competitive advantage. At the end of the course, students should be able to do a thorough strategic analysis of any organisation starting from the formulation stage until the drafting of the implementation plan to ensure successful implementation of the strategy. The following are the learning outcomes for students...

Students have the opportunity to make a worthwhile contribution to business, by applying, the knowledge and skills accumulated over the years and hence, build up self-confidence before moving out into the business world as graduates.
