Techniques for the assessment of the information requirement are:-
1. Asking Questions –
a. Very commonly used method for the assessment of the information requirement.
b. Involves asking the questions to the persons associated with the use of the system, mainly to get their requirements.
c. Some asking methods can be understood well from the table that follows –
| S.NO. | Asking Method | Description | Conditions Suggesting Use |
| 1. | Closed Questions | Every question is consisting of the set of the possible answers that are usually very well defined and from these, the respondent can select. | Analyst is of great need especially when the group of the factual responses is not able to recall the different responses and also the possibilities. |
| 2. | Open Questions | Consists of no answers and the respondent is free for carrying out the formulation of the various types of the responses. | i. These include such scenarios when the feelings or the views are of great importance.
ii. Also when the respondent is having descent knowledge and also possesses the ability for the formulation of the different responses. |
| 3. | Brain storming | Group method for the elicitation of the various suggestions with the help of the open flow of the ideas. | Helps in the extension of the limits of the spaces of the problems of the various involved participants and elicit the non conventional solutions. |
| 4. | Guided Brainstorming | Various ideal situations are to be defined by the different participants and the most suitable and the best feasible ideal solution is selected. | i. Plays a very critical role in acting as the guidance for the brainstorming to the ideal solutions.
ii. Acts as a great help for the participants having the system knowledge. iii. One point very critical in such a scenario is that it may be locked in to the anchoring and the adjustment of the behavior. |
| 5. | Group Consensus | The estimates and the various expectations are obtained from the different participants about the various significant variables. Suitable examples include Delphi Method and the Group Forming. | The best judgmental estimates of the various variables can be obtained but only those variables are included that are very difficult to estimate quantitatively. |
2. Deriving from an existing information system
a. The information requirement for any proposed information system can be obtained with the help of the information systems that are in operation currently or also possess any type of the operational history.
b. For the achievement of the above explained point, the use of the various information systems is a must, so now it’s very useful to completely understand the types of the information systems that help play a vital role in such a scenario and the so the various types of the information systems can be summarized as the follows –
A. Existing system to be replaced by the new system.
B. Existing system in another, similar organizations.
C. Information that is available from the hand books, the industry, the specific studies or the different textbooks.
3. Ends Means Analysis
a. Very useful technique.
b. Helps in the determination of the various types of the information needs of the organization at the department and the individual manager’s level.
c. Helps in the separation of the definition of the ends that are generated by the organization process from the means, used for their accomplishment.
d. The outputs from one process acts as the input for the next process.
e. The ends means analysis brings out the critical information needs in a very effective manner.
What are The Critical Success Factors (CSFs)?
a. Act as a small number of the operational goals shaped by the industry and which can be easily identified.
b. Help a great deal in the determination of the information requirements of an organization.
c. These goals generally are assumed to be the assurance of the success for any organization.
d. On the achievement of these goals, the success of the company is almost guaranteed.
e. The critical success factors can be reached with the help of the large number of the methods but very commonly used method is the personal interview method.
f. With the help of the Critical Success Factors, smaller set of the data can be produced, which further can be analyzed but one very important point to kept in mind here is that the data which may be produced may be just aggregated without undergoing any type of the rigor analysis .
Business Systems Planning (BSP)
a. Also generally referred to as the Enterprise Analysis.
b. The Business Systems Planning is a method that is very much dependent or based on the process.
c. Was developed by the IBM in the 1960s.
d. At that time, was usually used for the establishment of the relationship between the large system development projects.
e. The Business Systems Planning is a top down method.
f. This method helps a great deal in the determination of the information requirements and also the information architectures.
g. The Business Systems Planning also plays a very critical role in the identification of the various key entities and the different attributes in the data of the particular organization.
h. The various steps are involved in the process of the Business Systems Planning and these can be summarized as the follows –
I. Achieving the commitment.
II. Proper preparation for the study.
III. Starting the study.
IV. Defining the business processes.
V. Defining the data classes.
VI. Analyzing the current systems support.
VII. Knowing the executive perspective.
VIII. Defining the findings and the various conclusions.
IX. Developing the recommendations and the action plan.
X. Reporting the results.
