Question

The end user is not the person in the organization most involved in the systems analysis and design process Answer T F Systems analysis is the second phase of the systems development life cycle. Answer. T F The main goal of systems analysis and design is to improve organizational systems, typically through applying software that can help employees accomplish key business tasks more easily and efficiently. Answer. T F Application software is also called a system. Answer. T F An information system does not include hardware and systems software. Answer: T F Methodologies are a sequence of step-by-step approaches that help to develop the information system. Answer. T F Techniques generally only provide support for one task. Answer. T F Techniques are processes that you, as an analyst, will follow to help ensure that your work is well thought-out complete, and comprehensible to others on your project team. Answer. T F CASE is an example of a tool. Answer. T F A system is an interrelated set of business procedures used by one business unit, working together for a purpose. Answer T F A component is the line that marks the inside or outside of a system. Answer T F A boundary often is called a subsystem. Answer. T F Components are most likely interrelated. Answer: T F

Explanation / Answer

1)Answer: True

Explanation:

End user:

The end user is the individual who uses the product after it has been fully developed and marketed. The term is useful because it distinguishes two classes of users, users who require a bug -free and finished product (end users), and users who may use the same product for development purposes. The term end user usually implies an individual with a relatively low level of computer expertise. Unless you are a programmer or engineer, you are almost certainly an end user.

2)Answer: True

explanation:

Following are the seven phases of the SDLC

1. Planning

This is the first phase in the systems development process. It identifies whether or not there is the need for a new system to achieve a business"s strategic objectives. This is a preliminary plan (or a feasibility study) for a company"s business initiative to acquire the resources to build on an infrastructure to modify or improve a service. The company might be trying to meet or exceed expectations for their employees, customers and stakeholders too. The purpose of this step is to find out the scope of the problem and determine solutions. Resources, costs, time, benefits and other items should be considered at this stage.

2. Systems Analysis and Requirements

The second phase is where businesses will work on the source of their problem or the need for a change. In the event of a problem, possible solutions are submitted and analyzed to identify the best fit for the ultimate goal(s) of the project. This is where teams consider the functional requirements of the project or solution. It is also where system analysis takes place—or analyzing the needs of the end users to ensure the new system can meet their expectations. Systems analysis is vital in determining what a business"s needs are, as well as how they can be met, who will be responsible for individual pieces of the project, and what sort of timeline should be expected.

There are several tools businesses can use that are specific to the second phase. They include:

3. Systems Design

The third phase describes, in detail, the necessary specifications, features and operations that will satisfy the functional requirements of the proposed system which will be in place. This is the step for end users to discuss and determine their specific business information needs for the proposed system. It"s during this phase that they will consider the essential components (hardware and/or software) structure (networking capabilities), processing and procedures for the system to accomplish its objectives.

4. Development

The fourth phase is when the real work begins—in particular, when a programmer, network engineer and/or database developer are brought on to do the major work on the project. This work includes using a flow chart to ensure that the process of the system is properly organized. The development phase marks the end of the initial section of the process. Additionally, this phase signifies the start of production. The development stage is also characterized by instillation and change. Focusing on training can be a huge benefit during this phase.

5. Integration and Testing

The fifth phase involves systems integration and system testing (of programs and procedures)—normally carried out by a Quality Assurance (QA) professional—to determine if the proposed design meets the initial set of business goals. Testing may be repeated, specifically to check for errors, bugs and interoperability. This testing will be performed until the end user finds it acceptable. Another part of this phase is verification and validation, both of which will help ensure the program"s successful completion.

6. Implementation

The sixth phase is when the majority of the code for the program is written. Additionally, this phase involves the actual installation of the newly-developed system. This step puts the project into production by moving the data and components from the old system and placing them in the new system via a direct cutover. While this can be a risky (and complicated) move, the cutover typically happens during off-peak hours, thus minimizing the risk. Both system analysts and end-users should now see the realization of the project that has implemented changes.

7. Operations and Maintenance

The seventh and final phase involves maintenance and regular required updates. This step is when end users can fine-tune the system, if they wish, to boost performance, add new capabilities or meet additional user requirements.

3)Answer: True

Explanation:

The main goal of systems analysis and design is to improve organizational systems, typicallythrough applying software that can help employees accomplish key business tasks moreeasily and efficiently

5)Answer: False

Explanation:

The basic components of computer-based information systems are: Hardware- these are the devices like the monitor, processor, printer and keyboard, all of which work together to accept, process, show data and information.

6)Answer: True

Explanation:

methodology should have set of stages and steps,which need to be followed in sequence if the work is to be done successfully.

8)Answer:False

Explanation:

machine learning techniques provide support and solution for knowledge discovery in many areas of health care.

11)Answer:True

Answer:

system is an interrelated set of components with identifiable boundary working together a purpose
