Explanation / Answer
BPR management technique to a business organization the implementation team effort is focused on the following objectives:
Customer focus. Customer service oriented processes aiming to eliminate customer complaints.
Speed:
Dramatic compression of the time it takes to complete a task for key business processes. For instance, if process before BPR had an average cycle time 5 hours, after BPR the average cycle time should be cut down to half an hour.
Compression:
Cutting major tasks of cost and capital, throughout the value chain. Organizing the processes a company develops transparency throughout the operational level reducing cost. For instance the decision to buy a large amount of raw material at 50% discount is connected to eleven cross checkings in the organizational structure from cash flow, inventory, to production planning and marketing. These checkings become easily implemented within the cross-functional teams, optimizing the decision making and cutting operational cost.
Flexibility:
Adaptive processes and structures to changing conditions and competition. Being closer to the customer the company can develop the awareness mechanisms to rapidly spot the weak points and adapt to new requirements of the market.
Quality:
Obsession with the superior service and value to the customers. The level of quality is always the same controlled and monitored by the processes, and does not depend mainly on the person, who servicing the customer.
Innovation:
Leadership through imaginative change providing to organization competitive advantage.
Productivity:
Improve drastically effectiveness and efficiency.
2)business area:
The business area is the company's operations. Fixed assets and accounts receivable may be balanced in accounting using business areas.
Examples of business areas include product lines, subsidiaries, and branch offices.
5)CURD diagrams: CRUD matrix is a table showing the Functions in an application containing SQL statement affecting parts of a database.use curd digrams
group data entities into subject databases,
group business functions or processes into business areas, identify areas that should be examined for problems, such as: data entities not created or used by any business function or process, business functions or processes not accessing any data entities and data entities that are created by more than one business function or process.
7)SDLC:
The systems development life cycle (SDLC), also referred to as the application development life-cycle, is a term used in systems engineering, information systems and software engineering to describe a process for planning, creating, testing, and deploying an information system.
The Waterfall Model was the first Process Model to be introduced. It is also referred to as a linear-sequential life cycle model. ... The Waterfall model is the earliest SDLC approach that was used for software development. The waterfall Model illustrates the software development process in a linear sequential flow.
