Testing, Evaluating and Maintaining

(Pg 90 -101 of text)
Tasks included are:
1.       testing and evaluating the solution with test data such as
        volume data – test data (data that is made up – guessing the problems that may arise)
                                                               i.      designed to ensure the system works within the requirements
                                                             ii.      how does the system form with large amounts of data – based on the number of data that has been entered
                                                            iii.      computer programs generate the millions of data
        simulated data – test data
                                                               i.      Could contain unexpected values – numbers instead of letter or vice versa etc.
                                                             ii.      Replicate operational conditions, e.g. many users, many connections, other processes occurring at the same time.
        Live data – real data that is encountered in a normal operation of a system.
                                                               i.      Real world data, no one has generated it, it’s what the system works with.
                                                             ii.      E.g. types of data and scenarios that have not yet been predicted that could cause a problem.
2.       checking to see that the original system requirements have been achieved
        acceptance testing – test to see if the system meets the requirements
        once the acceptance testing is passed it proceeds to pay the bill
        often outsources this process
        those doing the acceptance testing – either the user or the external party
        focus groups for acceptance testing – expose different groups to the system to receive opinion on data
        occurs with an agile method where it is ongoing
        traditional – will be done finally after implementing
3.       trialing and using the operation manual
        doesn’t just tell you how to use it
        describes procedures and policies
        procedures – step by step methods
        policies – rules or guidelines
4.       reviewing the effect on users of the information system, participants and people within the environment
        the changing nature of workplace
        telecommuting:-  more workers are now able to work from home through the internet
        disadvantages: lack of social skills, blurring with workplace and home which can increase stress
        advantages: flexibility in work times and childcare arrangements and avoidance of commuting costs and time lost during commuting
        Social Isolation’
        Deskilling:  some work previously covered by workers are no longer required, can cause redundancy of jobs
5.       modifying parts of the system where problems are identified
        After evaluating any problems that are detected need to be altered and modified.

Implementing : Training Methods


·         Group training method
o   Advantages: allows the participants in the training to ask questions
o   Disadvantaged: if you can’t keep up you get lost.
o   Pace can be either too fast or too slow
o   Cost efficient and time efficient
o   Requires a follow of the tasks
·         Peer training (one on one training)
o   Advantages: allows the participants in the training to ask questions
o   Pace is efficient and can be done in your own pace.
o  
·         Online training
o   Pace: determined by the participant
o   Can’t adapt to the participants needs
o   Potentially always up to date
o   Everybody has immediate access.
·         Operational manuals
o   Pace is also determined by the participants.
In real life a combination of all should be implemented,  for example starting with a group method then consulting one on one and proceeding to online and operational manual methods.
