Definition Of Fact Finding Techniques Information Technology Essay

Definition Of Fact Finding Techniques Information Technology Essay Introduction Requirement analysis can be said to identify investigation, documenting and analysing requirements of the system. The first investigation step of the need of a system is a major activity of problem analysis. This is the role of a system analyst to determine the actual requirement of a system. Sometimes, system analyst may make mistake in discovering the requirements and in trying to analyse a problem. As a result, they may come up with the wrong solution in designing and implementation of a solution. And the solution will not be able to solve the real problem and even cause a new problem in later system analysis process. Therefore, this paper looks at one of the effective methods (fact-finding) for system analyst to help them in gathering information. Definition of Fact-finding Techniques Fact finding is process of collection of data and information based on techniques which contain sampling of existing documents, research, observation, questionnaires, interviews, prototyping and joint requirements planning. System analyst uses suitable fact-finding techniques to develop and implement the current existing system. Collecting required facts are very important to apply tools in System Development Life Cycle because tools cannot be used efficiently and effectively without proper extracting from facts. Fact-finding techniques are used in the early stage of System Development Life Cycle including system analysis phase, design and post implementation review. Facts included in any information system can be tested based on three steps: data- facts used to create useful information, process- functions to perform the objectives and interface- designs to interact with users. Fact-finding techniques There are seven common fact-finding techniques Sampling of existing documentation, forms and databases Research and Site visits Observation of the work environment Questionnaires Interviews Prototyping Joint requirements planning Sampling of existing documentation, forms and databases The best way to analyse the existing system is to collect facts from existing documentation rather than from human sources. There are various kinds of documents to collect facts from existing documents. These include: e-mails, customer complaints, suggestion box notes and reports that document the problem area problem performance reviews, samples of completed manual forms and reports and samples of completed computerized forms and reports various types of flowcharts and diagrams, program documentation and user training manuals System analyst uses sampling techniques in order to organize the above documentation. Sampling technique is the process of combing a representative sample of documents, form and records (Bentley, Whitten, 2007). According to these authors there are two commonly used sampling techniques namely randomization and stratification. Randomization is the process of selecting sample data randomly. Stratification is the systematic process to deduct the variance of sampling data. We can have better understanding of the system due to the analysis of existing documents, forms, files related to the current system. Research and Site visits Research and site visits, second technique, is the process of examining the problems which had previously solved by other sources that can be either human or documents. To solve the requirements of problem, the analyst visits to other organization that had previously experienced for similar problems. In addition, the analyst can also find the information from database, reference books, case studies and Internet. Advantages of Research and Site visits It can save the time if the problem is already solved. Researcher can know how different person previously solved the same problems. Researchers always know the details information about the current development system. Disadvantages of Research and Site visits Need authority to access the appropriate source of information. As documentation of problem is not recorded, there is difficult to solve the problem. Observation of the work environment Another fact finding technique is observation. In this technique, system analyst participates in the organization, studies the flow of documents, applies the existing system, and interacts with the users. Observation can be a useful technique when the system analyst have user point of view. Sampling technique called work sampling is useful for observation. By using this technique, system analyst can know how employees spend their days. Questionnaires Questionnaires are also one of useful fact-finding technique to collect information from large number of users. Users fill up the questions which are given by the system analyst and then give the answers back to the system analyst. Questionnaires can save time because system analyst does not need to interview each of users and if the time of interview is short, questionnaires are more useful. To fulfil the requirements of the system objective, system analyst should have the ability to clearly define the design and frame of questionnaires. There are two types of questionnaires: Free-format questionnaires In free-format questionnaires, users are allowed to answer questions freely without immediate response. The results are also useful in learning about feelings, opinions, and experiences of the respondents. Fixed-format questionnaires The purpose of fixed-format questionnaires is to gather information from predefined format of questions. Users are allowed to choose the result from the given answers. There are three types of fixed-format questions: multiple-choice questions (Yes or No type), rating questions (Strongly agree, Agree, No opinion, Disagree, Strongly disagree), ranking questions (numbering according to the preferences). Advantages of Questionnaires People can fill the forms and give answers freely to the analyst. This technique is inexpensive. Users are more willing to response real answer as they do not need to give their personal information. Responses can be calculated and analysed quickly. Disadvantages of Questionnaires Incomplete answers will be received from users. Analyst cannot observe the body language of user responses. Analyst has no chance to define vague or incomplete responses. Good questionnaires are difficult to prepare. Interviews Interview is the most commonly used technique to collect information from the face-to-face interviews. The purpose of interview is to find, verify, clarify facts, motivate end-users involved, identify requirements and gather ideas and opinions. The role of interview includes interviewer who is system analyst and interviewee who are system owner or user. Interviewing technique needs good communication skills for interaction between system analyst and user. There are two types of interviews. Unstructured interviews An interview that is conducted with only a general goal or subject in mind and with few, if any, specific questions (Bentley, Whitten, 2007). Open-ended questions type is used in unstructured interview that allows user to answer freely in an appropriate way. Structured interviews Structured interview is an interview which contains predefined set of questions. In structured interview, close-ended questions type is used to limit answers to specify choices, short and direct responses from the interviewees. Advantages of Interviews By motivating interviewees, they have confident to answer the questions more effectively. System analyst can examine the more feedbacks from the interviewees. System analyst can prepare questions for interviewees to be more suitable or change the questions for every individual. System analyst can know the nonverbal communications of interviewees by perceiving the body movements and facial expression. Disadvantages of Interviews Interviewing is time consuming and costly mechanism in fact-finding technique. Moreover, the communication skills of the system analyst affect the success of interview. Prototyping Another fact-finding technique is known as prototyping which collects the requirement facts of the system. Prototyping is sampling a small working model and it is more related to pre-design of the information system. The implementation of prototyping can be developed in earlier stage of system development life cycle when analyzing the facts. The process of prototyping facts in order to specify the userà ¢Ã¢â€š ¬Ã¢â€ž ¢s requirements is also known as discovery prototyping. Advantages of Prototyping Users and developers are able to test and understand the system in advance before final implementation. It also can make and determine development of the system before applying high development costs in the information system. In addition, it is a kind of training mechanism. Prototyping require less time on fact-finding and it is useful in defining the constant and consistent requirements. Disadvantages of Prototyping Training of developers is a requirement in prototyping. Sometimes users can misunderstand the performance, reliability and features of prototype as real results. Therefore, users need to train to know that prototype only covers system functionality and it is not a complete system. Development cost and schedule may change in prototyping. Joint requirements planning JRP is the structured group work meeting to identify, analyze problems and define the requirements of system. JRP is becoming increasingly common in systems planning and systems analysis to obtain group consensus on problems, objectives and requirements (Bentley and Whitten; 2007). JRP can tabulate the facts efficiently in a short time and it can also replace in the place of numerous and separate interviews. JRP contains different participants with each specialized roles to perform structured meeting. JRP participants include sponsor, facilitator, users and managers, scribes and IT staff. Sponsor is an individual in top management, who has full authority to decide who will be participants, time and location of JRP session. The role of facilitator is to lead JRP session, motivate participants, solve conflicts and meet the requirements of meeting during the JRP session. Users in JRP session are responsible for rules and requirement of business, prototype, and satisfactory decisions. An d Managers are responsible for projects, schedules and costs and training requirements. Scribes job is to record everything discussed in the meeting. IT staff responsible for models and documentation concerning with facts during the discussion. Advantages of JRP JRP is formed different individuals with various roles and covers both in users and in management levels. JRP saves time to develop systems as it is not required one-on-one interviewing of each participant within the organization. When JRP incorporates prototyping as a means for confirming requirements and obtaining design approvals, the benefits of prototyping are realized (Bentley and Whitten; 2007). Disadvantages of JRP Extensive training is required for JRP as it is a group form. Active participation of all individuals will results the solution of JRP sessions.

Conversion of Biblical Measurements

One of comedian Bill Cosbys most hilarious routines features a conversation between God and Noah about building an ark. After getting detailed instructions, a puzzled Noah asks God: Whats a cubit? and God responds that He doesnt know either. Too bad they couldnt get help from archaeologists on how to count their cubits today. Learn the Modern Terms for Biblical Measurements Cubits, fingers, palms, spans, baths, homers, ephahs, and seahs are among ancient forms of biblical measurements. Thanks to decades of archaeological digs, scholars have been able to determine the approximate size of most of these measurements according to contemporary standards. Measure Noahs Ark in Cubits For example, in Genesis 6:14-15, God tells Noah to build the ark 300 cubits long, 30 cubits high and 50 cubits wide. By comparing various ancient artifacts, a cubit has been found to equal about 18 inches, according to National Geographics atlas, The Biblical World. So lets do the math: 300 X 18 5,400 inches, which amounts to 450 feet or a little more than 137 meters in length30 X 18 540 inches, or 37.5 feet or just under 11.5 meters in height50 X 18 900 inches, or 75 feet or slightly less than 23 meters So by converting biblical measurements, we end up with an ark thats 540 feet long, 37.5 feet high and 75 feet wide. Whether thats large enough to carry two of each species is a question for theologians, science fiction writers, or physicists who specialize in quantum state mechanics. Use Body Parts for Biblical Measurements As ancient civilizations progressed to the need for keeping account of things, people used parts of the body as the quickest and easiest way to measure something. After sizing up artifacts according to both ancient and contemporary measurements, theyve discovered that: A finger equals about three-quarters of an inch (roughly the width of an adult human finger)A palm equals about 3 inches or the size across a human handA span equals about 9 inches, or the width of an extended thumb and four fingers Calculate More Difficult, Biblical Measurements for Volume Length, width, and height have been calculated by scholars with some common agreement, but measures of the volume have eluded accuracy for some time. For example, in an essay titled Bible Weights, Measures, and Monetary Values, Tom Edwards writes about how many estimates exist for a dry measure known as a homer: For instance, a Homers liquid capacity (though normally seen as a dry measure) has been estimated at these various amounts: 120 gallons (calculated from footnote in New Jerusalem Bible); 90 gallons (Halley; I.S.B.E.); 84 gallons (Dummelow, One Volume Bible Commentary); 75 gallons (Unger, old edit.); 58.1 gallons (Zondervan Pictorial Encyclopedia of the Bible); and about 45 gallons (Harpers Bible Dictionary). And we need to also realize that weights, measurements, and monetary values often varied from one place to the next, and from one time period to another. Ezekiel 45:11 describes an ephah as being one-tenth of a homer. But is that one-tenth of 120 gallons, or 90 or 84 or 75 or ...? In some translations of Genesis 18: 1-11, when three angels come to visit, Abraham instructs Sarah to make bread using three seahs of flour, which Edwards describes as one-third of an ephah, or 6.66 dry quarts. How to Use Ancient Pottery to Measure Volume Ancient pottery offers the best clues for archaeologists to determine some of these biblical volume capacities, according to Edwards and other sources. Pottery labeled bath (that was dug up in Tell Beit Mirsim in Jordan) has been found to hold about 5 gallons, comparable to similar containers of the Greco-Roman era with capacities of 5.68 gallons. Since Ezekiel 45:11 equates the bath (liquid measure) with the ephah (dry measure), the best estimate for this volume would be about 5.8 gallons (22 liters). Ergo, a homer equals roughly 58 gallons. So according to these measures, if Sarah mixed up three seahs of flour, she used nearly 5 gallons of flour to make bread for Abrahams three angelic visitors. There must have been plenty of leftovers to feed their family -- unless angels have literally bottomless appetites.

This is how you are to make it: the length of the ark three hundred cubits, its width fifty cubits, and its height thirty cubits. Ezekiel 45:11 The ephah and the bath shall be of the same measure, the bath containing one-tenth of a homer, and the ephah one-tenth of a homer; the homer shall be the standard measure.
