Testing, Evaluating and Maintaining
(Pg 90 -101 of text)
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.
