…,”the process of analysising a computer system starts with a broad look at the system which is then looked down into smaller parts. Each of the smaller parts can then be broken down into even smaller and so on. This approach enables a complete analysisi to occur without the initial task appearing to be a task so large as to be unable to be completed. the purpose of the analysis phase of the sysstem development life cyclce is to document what the current system does and highlight the strengths and defecienices in it. in the analyssis of the system the following should occur -identification and evaluation of sources of information-idenfitication and description of the yypes of information needed to analysise the system identification and description of information needed to design the systeminformation flow and needs documented using system modeling tools. idenfitication and description of problem areas in the current system

the analysis phase identification and evalutation of sources of information,”when deciding what type of network was required for a new information system 3 RRD management consulted staff extensively. View a (video) of Kath Latch, station manager dicuws this process IN order to run a analysis of a system the first step must be to idefnitify the sources of information that will provide views on the running of the current system. THis will include the users of the information the system produces, users of the actual system and people who support the system. Each of the groups will provide into that contributes to the construction of an overall picture of the running of the system. In each of the broad groups idenitifed above, there will be diffrent categories or subgroups within it. It is important important that input is recieved from all of those parties so that a well-balanced overall view of the system can be developted. In order to perform an analysis of a system a number of people must be consulted of the information the system produces, users of the actual system and people who support them when performning an anayalsis of the current system, the view of the users of the system are parmount in successfully recognising the strenght and idenfying weaknesses present. The first task of the analysit will be to identify who they need to consult to find out about the current system.In doing this, they will need to identify the following users of the system: those who provide data, those who input data, those minpulate the data and those who recieve data. As well as those who own or run the organization for they will also have ideas as to what the systemis doing what it can be doing or what it should be doing. Although you would imagine the dicussion with the users of the system would uncover this information

The analysis phase identification and description of the types of information needed to analayse the system,”having idenfitied the sources of information, the next step the analysis must take is to establish what information can be gained from them, The information which can be gained from them. THe infromation which can be gained from the manager will be diffrent from the customers and so on. The analuyst must decide what information should be obtained from each source identified. It is unsuaul for one use to be exlucsive source of information about the syustem most aspects of the system will have some degree of overlap- it may be that significant detail will come mainly from one source , but there will usually be other users who are also impacted and informatrion must be collected from them as well. As well as identifying who will be capable of supplying what information in this step the analayst must also make decesion about the reliability and sustainability of the sources. Information collected must be evalutated for bias and relevance and given the approrpriate weighting in the overall analysis of the system. For example, while a manager and a data clerk would both have opinions on the usefullness of the financial reports produced by a particuylar system, the maqnagers opinion would have more weighing, but conversely the data clerks opinionhas more significance in areas relting to the case of data entry. Sometimes the analyst will idenfitfy the need for other information in order for fully analyse the system. In this case, they would need to document where this information can be obtained
