Explanation / Answer

Question 1 :

Objectives of BPR:

The objectives of BPR are as follows:

1.The aim of the BPR is to gainperformance improvements in the speed ,cost, quality and output of the product or process that is being delivered to the clients.

2.To redesign the processes in terms of technological enhancements in order to improve operational effectiveness by streamlining the existing processes.

3.To divide the tasks into a set of workflow activities across all the organizational levels of the organization in order to facilitate smooth work effenciency as well to achieve the required targets and benefits expected from the product or service that needs to be delivered.

Question 2.

How is BPR consistent with the object and client/server models.

BPR is consistent with the object and client/server model because the main core or the basic functionality of both of these are quite similiar. As, the Client server model distributes the tasks such that client requests services from the server and the server allocates the tasks or work among the service providers.In the same way, BPR streamloines the workflow activities such that the required functionlaity is achieved by allocating the tasks properly across the different levels and expertise.

Also, Both Client/server model and BPR work towards common goal of enhancing and improving performance to gain effectiveness in providing service to clients.

Question 3.

What is a business area?

Business area is an area or department of operations in an organiztion that can be related to a particular business segment or an area of responsibility. For ,example business area can be related to financial accounitng to generate reports related to profit and loss.

Thus, Business area can generate reports for internal purposes of any company. It helps in the decision making and analysis process.

Question 4.

Explain the relationship between BPR and structured tools.

Structured tools assist in the design approach of structural thinking and implementation. Since, the aim of BPR is to redesign or structure the activities in such a manner that the customers or users of the service or product must find it effective in terms of ease of use, quality and performance, Structured tools helps in BPR.

Structured tools for example like DFD (Data flow diagrams) provides simulation of how the customer will interact with the system to be developed and thus it helps in describing the communication between the user and the product.

Thus, Structured tools provide following advantages to BPR as it helps by:

Question 5.

What is a CRUD diagram?

CRUD stands for Create,Read, Update and Delete functions that are used in Database handling operations.Thus, CRUD in any databse indicates the basic SQL commands that we use to perform operations on the data.

CRUD diagram is a matrix or table that shows the interralation between the different processes and the data involved for any system that is being developed.Thus, CRUD diagram shows graphically the links if there is relation between a process and data resource. Also, the links shows what operation is performed by a particular process on the data that is whether it is READ, UPDATE,DELETE or CREATE .

Question 7.

What is the SDLC? Why is it called a waterfall approach?

SDLC stands for Software Development Life cycle. SDLC is a application development paradigm that specifies a planned approach comprising of different phases which includes Requirements gathering, Design, Coding, Testing and mintenance phase respectively.

The most earliest and basic model of SDLC was waterfall model in which all the phases were sequentally executed one after the other which represented that of a waterfall.Thus, waterfall model is the easy and mostly used model of SDLC and hence SDLC is called as Waterfall approach.

Question 9.

What is the significance of the spiral approach and how does it support the development of reusable objects?

Spiral Approach is risk based SDLC model that utilizes the functionalities of all the other mosels mostly waterfall, ptotoyping and incremental model in which all the activities are repeated iteratively till all the uncertainties and risks are identified and resolved.

Since,The spiral model makes use of existing SDLC models and sometimes makes of already developed commercial off the shelf components it is said to support the resusable objects.

Question 12.

What is the difference between a transaction database and a data warehouse?

Question 13.

Briefly summarize the importance of the IT team in the go-live and support phases.   

IT Team plays an important role in the go-live and support phases because various activities need to be handled in case any issues or problems arises. These activities include following:

1.To provide on-site support during starting phase of go-live to ensure smooth functionality.

2.To handover system administration and documentation and manuals to client team

3.To handle any issues that might occur during the go-live phase

4.Enhacing and maintaining the system

5.Providing user support using help desk or 24/7 on call support

Transaction database Data Warehouse It is normalised database It is denornalised It has day to day transaction data It has historical data It is volatile as it maintains everyday transaction of a business It is non volatile as it is not updated daily only periodically It is used for OLTP( online transaction processing) It is OLAP( online analytical processing) used only for decision making and analysis purpose
