6. Part C – Critique of Use Cases and Rich Pictures
6.1. Comparison Between Rich Picture And Use Case
It is very important to use both of the techniques while playing the role of an analyst, because it is right approach to figure out the requirement process in two different ways (hard and soft) to produce the best solution.
Rich picture is the technique to look at the actual climate of the organization; it gives you a clear idea how system is working, who is involved in the system what issues they have, what is the structure of the system, what conflicts they have?
Rich picture gives you all the answers mentioned above, it helps understand the existence of the soft problems within the system; there is no special syntax for drawing the Rich Pictures.
Use Cases is the best technique to figure out the technical aspects of the system, it help you understand the functionality of the system and its interaction with the humans (Actors), the Use Case Diagram is best to present your requirements in terms of processes and it allows you sort out any errors before the implementation of ...
The Army problem solving, and the RDSP use measures to identify a problem. While the Army problem solving, process uses quantitative analytic tools in order to measure an effective outcome. By contrast, the RDSP uses running estimates (CCIR) which may include status of friendly forces, enemy forces, equipment, intelligence, movement, or fires.
Different application types require the use of various development techniques for a number of reasons. The below are a few such reasons:
Much like an experimental case study, it often uses variables. As with any other method, it has its advantages and disadvantages. The advantage of a case study is the ecological validity of it. The information that is used in these studies is from a real life environment. The information is good information because the research is so in depth.
Tabular Collection Diagram shows the process of the system, so it helps identify risks or problems in a system early on. Tabular Collection Diagram put requirements to the test and enables you to see if more requirements are desirable. A brilliant method to discover problem’s in the earlier stages of development.
way both works use and treat point of view and form, governmental systems and ideals the
One thing to remember when using any decision-making tool is to keep the end in mind. In other words when working through a process, visualizing the end result is Helpful. We must also remember that in every decision-making process there are a multitude of tools to help us along the way. No tool is really better then another, in fact most are made to compliment each other not as a soul solution to the process at hand.
They are both very powerful tools for team skill building. When team members can identify with the models and learn to move through each stage successfully, it can set organizational standards to new highs. Every business professional should want to keep a copy of these models on his desk because of the growing dependence of teams in organizations. After all, no one wants to be on the losing team. The ineffective team gives no pleasure or feeling of accomplishment to anyone involved!
The process of soft system methodology usually requires a lot of patience as there are several different steps through which managers have to go through in order to attain best results. Therefore, you cannot expect results to come at early stage and hence you cannot narrow the scope of investigation because the results then will not be appropriate. Moreover, it is difficult to assemble the richest picture, without imposing the particular structure and solution on problem situation.
There are various approaches towards a certain problem or strategy. Some approaches could fit in a given situation and not in another. Analytical/planned and emergent approaches have some differences as well as benefits and drawbacks. Analytical approach is that in which the vision, objectives and intentions of a firm are clearly stipulated and made known to the actors or staff as a way of realizing a certain outcome. It requires a clear vision, plans as well as formal controls aimed at enforcing them in a predictable environment. In this approach, external factors such as advancement in technology and change
I will first of all define business analysis as a practice of enabling change in an organization setting, by defining needs and recommending solutions that deliver value to stakeholders. Business analysis help businesses do better, it identifies and articulates the need for and how change in organization’s work and hence facilitate the change. Business analysis identifies and defines the solutions that will maximize the value delivered by the organization’s stake holders. The process of business analysis begins with the orientation were we get to understand or get the feel of what’s underway. Clarifying roles and determining primary stakeholders to engage in defining the project’s scopes and business objectives. Next in the process is to define
Make sure that their methodology is accepted by clients. Methodologies can be flexible enough to be adaptable according to customer’s demands. If the customer is not satisfied with the methodology, there is a great chance for failure in the project, and to lose the customer for further
After the systems planning is complete, the next course of action is the systems analysis phase. This phase includes defining the requirements of the system. This means that the team must conclude what the system needs to do in order to satisfy the users. This is done by forming a requirements...
Agile development is chosen when the requirements are not clear. This is the reason that it is chosen for the projects where the rate of risk is high. Agile software development is best for the projects where the project can be divided in mini projects and these mini projects are completed by passing through the phase of design, coding and testing. The results of these iterations clear the requirements gradually. The feedback from the customers also clears the requirements. This is the reason that most of the companies use agile development methodology because of the fact that it has the capability to adapt to difficult situation and chase strict deadlines. Agile method is being used all over the software industry. Most of the developers are aware of the fact that Agile methodology is best for them.
Williams, (1997) identified four steps to system planning. Earl (1989) proposed five alternate strategy frameworks which project managers should consider when deciding how the system will enhance the business function. Standard business strategy methods are used to identify such opportunities by using: value chains, application searching and information analysis (Earl 1989).
Before discussing, in the depth, the differences and similarities between both strategies above, let us first sum up, on a simple basis, the basic role of the architect in the procurement process.
