Chapter 8: Starting the Solution
Question 1. What is a persona and when is it used?
Answer: A persona is a virtual character that represents a large number of customers (or users) with similar characteristics or demographics. Personas are constructed from data collected through surveys of your target audience and so represent most of your eventual users. It is important that you construct your persona with enough characteristics for you and your team to feel that they understand it well enough to know what it wants.
Personas are used when you have a large number of in-house users, or a large number of customers who will be using the product. The business analysts and designers use a persona as their source of user specific requirements.
Question 2. What do you mean by "Designing the User Experience" ?
Answer: Designing the whole of the user experience is the best way to come up with a product that makes people want to buy it and/or use it. Experience design aims to produce a usage experience that is pleasing and exciting, as well as relevant to the culture and aspirations of the user. Such design focuses much more on how the product makes the user feel than on adding functionality to the product. The business analyst is not the experience designer, but he has an understanding of the essential business functionality and non-functionality. This knowledge, along with any personas generated or observations of users during the requirements activity, provides the input to experience design.
Question 3: What is a business event and explain the real origin of the business event.
Answer: Events that take place in the course of normal operation for a business that reoccur as business processes are executed. Business events must be defined in the process of automating business practices, in order to set up notifications, reports, alerts, and other business process automation features.
The business event almost always originates outside the work when the adjacent system does something. The real origin of the business event often occurs well before our systems think it does.
Question 4: What is an autonomous adjacent system?
Answer: An autonomous adjacent system is some external body, such as another company, a computer system, or a customer, that is not directly interacting with your work. Autonomous adjacent systems communicate through one-way data flows such as letters or e-mails or online forms where no back-and-forth interaction is possible. It acts independently of the work being studied. For example, when your credit card company sends you a monthly statement, you (the card holder) are an autonomous adjacent system. You passively receive the statement with no interaction. You are acting independently, or autonomously, as seen from the viewpoint of the work of the credit card company.
Question 5: Explain Cooperative adjacent systems.
Answer: Cooperative adjacent systems are automated systems that collaborate with the work during the course of a business use case, usually by means of a simple request–response dialog. A cooperative adjacent system might be an automated system containing a database that is accessed or written to by the work, an automated system that does some computation for the work, , or any other automated system that provides a predictable and immediate service to the work. Because so much of the functionality of our organizations has been automated, several cooperative adjacent systems almost always appear in your context model.
Personas are the fictional and imaginary characters which you can create on the basis of your knowledge and used to represent a group of people. It is quite useful to know the end user of the product or service. Although we conduct interviews and do surveys to know the reactions of the end user of the product what when there are multiple end users involved and multiple stakeholders involved in the project who are not readily available for an interview then we can use personas.
ReplyDeleteTo come up with the solution to the problem we have defined in the previous chapter, we move to the last quadrant of the Brown Cow model, moving from the Future-What quadrant to the Future-How quadrant. At this stage, a business analyst, with a solid understanding of the essence of the business, is applying available technology on business solutions. This process is called starting the solution as mentioned in the title of this chapter. One important task before starting this phase is that a business analyst will have collected a good chunk of the functional needs and a significant portion of the non-functional needs for the work that he has been studying. Moreover, a business analyst will have collected these as essential, or technology-free, needs.
ReplyDeleteA business event is a definable occurrence in a business scenario. It can be a common high-level occurrence, such as a customer placing an order. Alternatively, it can be a more specialized event, such as a customer exceeding a credit limit while placing an order. Some events can be triggered by changes in values, such as the share price for a particular stock exceeding a given value.
ReplyDeleteBusiness events define significant happenings that different parts of the business must register and act upon by using different applications.
