Decision Support Systems (DSS)
1. Abstract: Decision making plays a very important role in the organisation. The organisation may be any industry, company or a factory. The success of organisation depends on the decision taken by the organisation. Decision is a kind of judgement to select the best one from available action. Basically decision support system is a system which supports the decisions of management in the organisation. The system supports the decisions taken by the management of the organisation for the success of the organisation. {0}
2. Introduction:
Decision support systems (DSS) are a class of computerized information system that support decision-making activities. Decision support systems are designed artefacts that have

Model Base Management System:
This system is divided into two major parts:
Pre written Computer Program: It may include mathematical and standard models as well as special program developed for an individual manager and organisation or an industry. In addition the model base includes the simulation program and sensitivity analysis routine.
Model building blocks: Some of pre written programs and sub routines can be used to construct an application. The model base management system is a software system that records updates and changes the data manipulation. It is capable of creating relations between the updates and the database.
4.3. Decision Making Model:
• It consists of identifying the problems,
• After identifying what the problem is the decision maker must get a data and separate them from opinions.
• Then understand the problem, to generate solutions and test solution for the feasibility. (Normally a problem can be solved in many ways. If there is only one alternative no decision is required. But in any rational decision making process the manager should not jump on to work single proposal without considering all the

• Data retrieval capability.
Above all
• Improve personal efficiency
• Expediting problem solving
• Facilitating interpersonal communications
• Promoting learning and training
• Increasing organizational control{5}
7. Disadvantages of Decision Support System:
Decision Support System can create advantages for organizations and can have positive benefits, however building and using Decision Support System can create negative outcomes in some situations.
1. Monetary cost: Some analysis for Decision Support System needs the advance of data analysis, statistics, econometrics and information system, so it is the high cost to hire the specialists to set up the system.
2. Information overload: Too much information is a major problem for people and many Decision Support System increase the information load. Although this can be a problem, Decision Support System can help managers organize and use information.
3. Transfer of power

8. Why use computerized DSS?
Computerized DSS can facilitate decision via:
• Speedy computations
• Improved communication and collaboration
• Increase productivity of group members
• Improve data management
• Quality support
• Using web anywhere anytime
For example, if Lowes head manager tells each of its workers that they are going to only serve people who ask for help because he is tired of seeing time wasted. This manager is only going by his side of things. While step 7 is implemented it is not successfully used. While being used in the Lowes manner, “Implementing the Decision” as team to allow each hardware section to decide whether to ask each customer they see if they “need help,” or wait for the customers to ask the employees. Allowing for each team member to change methods and accomplish step 8 by “Evaluating the Decision.”
It was impossible to find a method to keep balance between these two ideas. For the second reason, I think that it should make the decision about those
This allows them to make the most accurate decision that they could with the information
Quality Assurance Interview with Doug Smith There are many issues facing quality assurance within healthcare organizations. To help understand these complex issues I interviewed Doug Smith, who is the Data Quality Manager for the 489th Aerospace Medicine Flight on Dyess Air Force Base. According to Mr. Smith, the top five issues that are facing quality assurance are problem identification, leadership, employee participation, data collection, and sustainability (XXXX).
This detailed design should be easily converted to programming logic. It is at this stage the technology specifications for implementing the solution, logical structure of the application, design of WebPages, database designs etc are finalized. Test plans and test cases for the application are devised at this stage. Implementation phase – 5 weeks This stage involves implementing the design documentation using the technologies and platforms decided .For
One of the most common action that businesses as well as individuals needs to face on a daily basis is a decision making process. Some of the choices can be difficult, other very simple , yet no matter on the situation these choices can have a large impact on our future life. As we are all aware, conflict can occur very fast and easily, so for the same reason it is important to learn how to effectively deal with these kind of problems. There are many different techniques which we can use while reducing the tension , yet the six step model process is known as the most effective.
It is a systematic method that utilizes knowledge, measures, and environmental analysis to produce the most ideal solution. Each decision is analyzed based on its possible consequences with an emphasis on short and long-term solutions. These processes require ample amounts of information, time, and people. While quality solutions are produced, the willful choice model does not allow for flexibility regarding environmental changes such as technology and healthcare policy. Internal changes including turnover also negatively impact the rational decision process.
A decision is the thought process of choosing between two or more outcomes that may or may not have a great impact. When thoroughly pondered, living life is fundamentally based on making the best decisions. Whether or not they are great or small decision making is critical. Often times, it is the smallest decisions one can make that impact the even bigger decisions later to come. Starting from the time people wake up in the morning, the will be surrounded by the most basic decisions until they go to sleep that night.
Prioritizing the Triple Constraint One of the first tasks a project manager is faced with is the prioritization of the Triple Constraint; this can only be done by communicating with the client whether the client understands project management or has ever heard of the triple constraint, in their mind, they already know what is most important to them. If your job is project manager, is to find this out, this is usually done by asking them a series of very, well worded questions. As you master the skill of balancing the triple constraint you will naturally begin to keep track of all aspects of project management and you will begin to understand what to look out for and at what stages of a project you should. Client Concerns and Priorities Generally,
Without a formal procedure, the contributory factors to the process are difficult to conclude. Preferences and values of decision-makers vary and are inconsistent. The discussion may be hindered and the effectiveness of the model is limited (Guy,
Q. 2. Recent development in Technology has enabled huge global organizations to avail information easily in their premises for smooth functioning of various departments within an organization. Much of a company's success comes down to its Supply Chain Management and logistics. The development of Information Systems in SCM helps in cost reductions, customer satisfaction and productivity.
What barriers to decision making are evident in this case? Diverse community and speaking multiple languages will make it time consuming job. Some members who have knowledge about any specific thing from the community will dominate the discussion. The main barrier is lack of knowledge of the deployed technology in the community.
For example, Managerial, Marketing, and Production, financial. It follows systematic and traditional based decision-making concept such as game
'A psychological test is any procedure on the basis of which inferences are made concerning a person 's capacity, propensity or liability to act, react, experience, or to structure or order thought or behaviour in particular ways ' (The British Psychological Society). The psychometric tests which companies make use of when selecting among job applicants have the potential to provide us with information about the kind of skills which employers are really looking for and they do provide additional information to that available in skill surveys. Psychometric tests are most likely to be used for managerial and graduate vacancies, and are seldom used for manual vacancies. The costs of these tests are substantial. This implies that
Relational Database Management System: This type of database management system that stores the data in the form of related tables. It is a social database administrator which deals with some typical kind of queries and uses SQL for the development of the database. This type of database is a very powerful database as it deals with the relations which makes the data manipulations easier other than any other database. It has the features of data entry, data deletion, and creating of new entry and records etc. the database provides the ease of accessing and maintaining data easily.
