  • Jahidul Islam Bangladesh t's not testing! You are not finding faults to fix - they should have been found and fixed well before the system was implemented. Evaluation measures how well the original ambitions of the new system (i.e. the logical design laid down during the analysis phase) have been achieved. Evaluation doesn't really serve to improve the system that is being evaluated; it serves to improve the next system you will work on. You learn lessons for next time when you evaluate. Different systems will have different criteria that demonstrate their effectiveness or efficiency. Just make sure that the criteria you evaluate are relevant to the goals the system was supposed to have when it was originally analysed. For example, if you buy a cow, you don't evaluate its speed, and if you buy a greyhound, you don't evaluate its milk output. Typical evaluation criteria include: speed accuracy quality of output reliability cost of operation attractiveness ease of use robustness capacity compatibility with other systems functionality (does it have the features it needs?) security flexibility (can it be upgraded, modified, adapted, tweaked, configured?) size, portability. valuation criteria describe what features will be measured. Evaluation methods describe how they will be measured. Don't get them confused! Whenever the word "efficiency" pops up, you should automatically be thinking: "time, money, effort/labour". So let's use them as a structure for an answer. To evaluate time efficiency, you could look at the time taken to: start the system enter data process data produce output communicate information maintain the hardware and software. To evaluate economic efficiency, you could look at the costs of: initial purchase costs of hardware, software, installation, consultancy training and documentation wages consumables repairs, upgrades, maintenance, service contracts interest rates, leasing costs To evaluate labour efficiency, you could look at: the number of staff required to operate the new system (e.g. the old system may have required 2 people, whereas the new system only requires 1 person) the number of man-hours spent operating the system (e.g. the new payroll system may take half the time to process weekly pay runs than did the original system. Typical evaluation methods include: timing how long an operation takes counting errors recorded in an error log visually inspecting output for quality, listening to sound reproduction counting and assessing incidents of failure or downtime observing users to see how quickly they learn to use the new system, how often they need help or make errors stress-testing the system or abusing it in ways that would be expected in real-life operation using the system to its stated capacity, or beyond (e.g. filling a database or hard disk drive) using the system in conjunction with another system to see if data and hardware are compatible carrying out functions to see if they exist and work as expected attempting to break into the system or get access to secured data attempt to configure the system to different users, or add modules, or change the way it works to suit new needs weigh it, measure it, carry it around to see if it's comfortable. After implementation, but how long after? o If you wait too long, users remember less about the development process and how it might be improved o If too soon, users have insufficient time to assess system strengths and weaknesses Six months of operation is desirable, but pressure to finish sooner often exists. Wait until the system is 'bedded down' and users are familiar with it, then evaluate whether it has solved the original problem. Has it achieved the goal specified in the Problem Analysis? If not, fix the thing! Don't sit around with a new system that is as bad, maybe worse, than the old system. Ideally, post-implementation evaluation should be performed by people who were not involved in the development process. External auditors often are involved, since they are impartial and don't have a stake in the success or failure of the system.

  • bwili Joseph Tanzania Now, i found how the problem ca be seen and how it could be solved not only in society even in our families there are many problems which need solution.management is needed to simplify things.

  • Odongo Moses Uganda The evaluation of the system is not a finite event that concludes with the project meeting the design goals. It is a regular process that continually reviews the system and researches for deficiencies and areas where improvements can be made. Once design goals and performance targets have been met the cycle can be considered over, but the cycle, can begin again -

  • Caroline Omoro Kenya How can one identify and address gaps in the system in evaluation phase?

  • Caroline Omoro Kenya The use /evaluation phase is the last phase of the system development life cycle.It involves auditing of the system and evaluation for further productivity.the process does not end with the project meeting the intended goals but ensures that the cycle begins again.

  • SRIPAD DEVRAO KULKARNI India Apart from the above phases of SDLC, another important activity is proper PROJECT CLOSURE. A project should be closed properly and client should sign-off the closure. Also problems faced/lessons learnt during the implementation of project be properly documented so that you don't commit the same mistake in future projects.
