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.
