Question paper 1

1. Section-A

   1. What are the component of MIS?

   Answer:

   MIS is made up of five major components as following:-

   1. Business producers :-Business producers are developed by the people. These are agree upon best practicals that guide the user and all other component on how to work efficiently.

   2. People:- The ICT department usually has supporting staff who ensure that the system is running properly. There are the user who use the information system to record the day-to-day business transaction fullstop the user are usually qualified professionals such as Accountants of and human resources manager.

   3. Data:- data is collected from activities such as withdraws deposit etc. Data is recorded day to day business transactions.

   4. Hardware:- it provide the computing power for processing data. It also provides networking and printing capabilities. Hardware is made up of the computers printer and networking devices.

   The hardware speed up the processing of data into information.

   5. Software:- system software and application software. These are the two major Paris is divided into.

   System software refers to the operating system. For example Windows

   Application software refers to specialized software for accomplishing business task such as banking system etc.

   So above are the five main component of an management information system.

2. 2. What are the important dimensions of information? Briefly discuss each. 

   Answer:

   Following are the different three dimensions of information system

   • Organizational

   • Management

   • Technology

   In the information system the management always need to make Bigg Boss season so to make better decisions management required to understand these three dimensions briefly.

   1. Organizational:- organizational dimensions management understand about what is embedded in its information. What kind of stuff is embedded in its information system. For example core task of organization hierarchy of organization culture and values etc for stop so manager is easily and dust and their organizational dimension of any organization. Because he is better away of his organizational culture and norms.

   Management should understand that all the decisions that they made a depend on the information which is provided by the information system.

   2. Management dimension:- manager is assisted bi information system to allocate resource, hiring of staff, motivating staff and realzing risky area are allocating experienced staff of such risky areas.

   Different type of design and new product are made by the manager.

   To reducing the cost of its product manager use Different techniques from information system like target costing.

   3. Technological dimension:- this include that technological and scientific achievement of any organization.

   So above are the three dimensions of information system source senior management is required to understand these three dimensions to make better decisions of the business through information system.

3. 3. Discuss the general model of human as an information processor. 

   Answer:

   A manager can be said to be an information processing because he is aur decision maker. By using is sensory receptors eye and ear to pick up information and then A transmit them to brain for storage.

   Then brain processes the information and give the response of which will become the final decision so in this way we can say that human is a a General model of information system.

   An intelligent manager also use the the accumulated knowledge from memory of processing the the information for final decision.

   The capacity of a manager to accept and process input to produce output is variable and Limited.

   Sometimes a situation is arises in which the complexity and amount of data is increase in UN a way that we can say is not able to process by the human mind. Because there is a limit of our mind it cannot handle huge burdent filtering is a process where by a manager selectively except that the type of input which are manageable to process by the mental ability.

   It is used to block unwanted or the inconsistent data.

   For this type of situation we need an experience manager who can easily handle the situation of because the experienced Manager mein automatic data or may draw innocent inferences. So we can say an experienced brain fit through situation. Because the knowledge and he she know how to do their.

   So understanding of the information is the ability to identify the correction and the casualty and the capability of the integrating and the information.

4. 4. What are the various levels of Management? Differentiate among them are with respect to different characteristics. 

   Answer:

   There are three main and various level of the management as follow

   • Strategic management

   • Tactical management

   • Operational management

   1. Operational management :- It is concerned with performing day-to-day business transaction of the organization.

   Structure decisions are made by user at this rule that guides them while making decisions.

   Cashiers are a point of sale, Bank tellers, Norse's in a hospital SSC staff are explained the user that are related to this level of management.

   2. Tactical management middle level manager head of the department commerce supervisors etc are comes under this level. This is also called an overseas level of management.

   Semi-structured decisions are made by the tactical users. The decisions are partly based on set guidelines and judgmental calls.

   We can understand it with an example and tactical manager can check the credit limit and payment history of a customer and decision to make an exception to raise credit limit of that customers.

   3. Strategic management level:- This is the most important level in an organization the user at this level make unstructured decision. Managers are concerned with the long-term planning of the organization. Their access information from external data as well as practical user to guide them when making unstructured decisions.

6. Section-B

   5. Briefly discuss the spiral model of system development. 

   Answer:

   Spiral model it is the base on unique risk pattern of a given project. It guys are term to adopt element of one or more process models. As waterfall or evolutionary proto types

   Spiral model is a risk device software device processing model.

   So as in the diagram spiral model has four phrases full stop a software project repeated by passing through to their phases in iterations called spirals.

   Identification phase:- identification of system requirement subsystem requirements product mature and Unity requirement for are done in this phase.

   This phrase is start with gathering the business requirement in the baseline spiral.

   It include the understanding the system requirement by continuing communication the customer and the system analyses. At the end of the spiral the product is deployed in the identify market.

   Design:- The phrase design start with the conceptual design in the base lines parallel and involve architecture design and logical design of module physical product design and final design in the sub segment spiral

   Construct or build:- This construct a phrase refers to production of the actual software product at every spiral.

   To get the customer feedback PUC proof of conduct is a developed in the bass lines parallel where the product is just thought of and the design is developed a PUC.

   Then in the subsurface segment parallel with higher clarity on requirements and design detail a working model of the software called build it is product with a vision number.

   Evaluation and risk analysis:- It include identifying explain meeting and monitoring the technical flexibility and management risk such as schedule page and cost overrun.

   The customer evaluates the software and provides feedback after testing the build add the end of the first iteration.

7. 6. Differentiate between structured and unstructured decisions with examples. 

   Answer:

   
    

   	Structured data	Unstructured data
   Technology	Relational database table	Character and binary data.
   transaction management	Matured transaction various concurrency technique	No transaction management con currency
   Version management	Versioning over tulles Ron's tables etc.	Versioned as a whole
   Flexibility	Schema dependent rigorous sachem	Very flexible action of scheme.
   Scalability	Spelling database scheme is difficult	Very scalable
   Rebuts ness	Very rebuts
   Query performance	Structured query allow Complex joins	Only textual queries possible
   Characteristics	Fix coded meaning and format of data from the beginning throughout complexion of business process deserved from transaction assigned to data fields easy to computer.	No fix format transaction transformation of mean into coded format Complex mostly desired from interaction cannot complaint.
   Data	Mostly numeric	Mostly non-numeric texture of text analogues
   User information	Data entry is fixed format	Data entry is non fixed format focused on communicate and interaction
   Example	Purchase order data with product ID supplier ID queries condition etc.	Image colors sounds shape blog form email calls social networking reading etc.

   
    

   So structured doesn't have a well-defined methodology for finding a solution and have that data to reach a decision.

   Unstructured decisions are made for general process and structure decisions are made for specific process like specialized manufacturing process.

8. 7. What are the applications of information system in production management. 

   Answer:

   Application of information system in production management.

   Management of operation in a production system is concerned with the decision making related to different component of the system so as to a compressed the Desire output.

   Production management applicator

   • Accounting

   • Quality of production with reproduction to a time-based.

   • Material requirement

   • Rejection quality

   • Breakdown incidence

   • Labor detail/ labor hours

   • Machine and facility utilization

   Query

   • status of job

   • Production program and job schedule

   • Status for availability of material

   • Standard information on machines

   • Standard on skills

   Production means application of process technology to the raw material to add the use and economy value to to arrive at a desired product by product by the best method with out sacrificing the Desire quality

   1. Production by disintegration

   2. Production by integration

   3. Production bi service

   Production Management is concerned with those processes which convert input into output

   It process of effective planning and requesting the operation of the section of Enterprises which is responsible for the actual transformation of materials into finished product.

   • Personal management

   • Financial management

   • Product management

   • Material Management

   • Marketing management

   The information system begins with the OLTP system user RDBMS for creating of database of for application development and SQL for querying add report generation.

   So production information system performs an integrating role with the production system of any organization.

9. 8. What are the various tool and model for decision support full stop discuss in short. 

   Answer:

   Tools and models for decision support:-

   Decision support tool is a software developed to sport analysis and decision maker in making better decisions and faster.

   Decision support tool that emerged web analysis with the powerful production capability can help complaints improve the way they approach information insight and the text that surrounds them.

   Information control :- this include gathering storage and Organization of data and information and knowledge include the information control.

   Models:- Paradigms models:- Paradigms frameworks for prospective that help one get a handle on a situation simulation model that enable answer to what if.

   Way of choosing:- This includes the technique or tool that analyses or help to narrow the field of choice.

   Representation ads:- this include tool and technique that add visualization of the data or problem space.

   Processor :- Processor are management technique that primary in R to control the some part of manufacturing operation. They may also provide or be based on party real prospective rather like the model above.

   DSS components: - database management system a DBMS collects organized error process data and information.

   DSS classification:- model divine DSS 8 uses data and parameter provided by user to assist the decision making in analyzing a situation.

   Communication driven by DSS:- Support more than one person working on us shorted task.

   Practical application:- DBMS allowed the organization facility assessed to and the evaluation of time series of the data.

   So above all the tool of that sport decision support in management information system.
