PIECESframework on Decision Support System

ThePIECES framework is very vital in determining the problems in aninformation system it is used as a checklist to detect the problemsin that system. There are various information systems which can bemonitored using the PIECES framework. This paper will evaluate theDecision Support System using the framework.

Problemsor opportunities in the system.

Performance.

  1. Throughput – The process of making decision using this system is very fast compared to the use of manual systems which involve a lot of activities and take alloy of time.

  2. Response time – The process of decision making is very fast using the system compared to when it is done manually.

Information(and data).

  1. Outputs.

  1. Sometimes the information produced from the support system is not accurate. This happens if the data input was not correct.

  2. The decisions made are sometimes not relevant.

  3. The decisions made may not be in the correct format and are thus not usable.

  4. The decisions may not be produced in the required time.

  1. Inputs.

  1. Sometimes, the data required for decision making is not captured.

  2. The data may not be captured in the required time resulting in wrong decisions or no decisions at all.

  3. The data may not be accurately captured. This leads to making wrong decisions.

  4. The data capturing process may be too difficult resulting in wrong decisions made.

  5. Illegal data maybe captured resulting in illegal decisions.

  1. Stored data.

  1. The stored decisions may be different for the same data input.

  2. The stored decisions may be incorrect.

  3. The decision may be inflexible meaning it does not allow any variations.

  4. Sometimes the stored decision may not be accessible.

Economics.

  1. Costs.

  1. It may be difficult to know the costs involved in creating the decision system.

  2. The costs may be hard to trace since it is hard to know the processes involved in decision making.

  3. It may be very expensive because decision making requires very complex programs and algorithms.

  1. Profits.

  1. It can help in faster decision making.

  2. It can lead to making of correct, effective and reliable decisions.

Control(and security).

  1. Too little control or security.

  1. The data may be subjected to people who are not authorized to see it and who may use it maliciously to make decisions which suit them.

  2. The regulations of the data may be violated.

  1. Too much security or control.

  1. Too much control may inconvenience users through making of inflexible decisions.

  2. They may also cause delayed processing and thus delayed decisions.

Efficiency.

  1. It will save a lot of time since decision support systems are very fast compared to people.

  2. It may not require a lot energy and resources like the manual decision making.

Services.

  1. The system may come up with incorrect decisions.

  2. The decision making process may not be easily understood by many people.

Methodsand research plan used.

Toanalyze the decision support system, I used two methods observationand interviews. First, I interviewed several people who useddifferent support systems. Using the PIECES framework, I asked themof the different challenges that they encounter using the decisionsupport system. I also asked them about its convenience over themanual decision making process.

Inobservation, I observed several decision support systems that are inuse. I also read about the reviews made by people regarding them fromthe internet. From these reviews, I was able to detect the problemsthat people encounter and also the benefits of using the decisionsupport systems.

Findingsand recommendations.

Thedecision support systems are very effective and reliable if they areused well. They save a lot of time since the use of computers is veryfast compared to processes done manually. It is very effective inmaking decisions that are based of large amounts of input data. Ifgiven accurate date, decision support systems produce accurateresults.

Whenusing a decision support system, the user should ensure that theyinput the correct data. They system uses the input data and thuscorrect data should be input for the system to make correctdecisions. The data should also be input at the correct time. Thishelps the system to make timely decisions. I can conclude thatdecision support systems are very important but only depend on theuser’s accuracy.
