A checklist for
identifying problems with an existing information system.
- Performance
- Throughput
- Response Time
- Information (and Data)
- Outputs
- Lack of any information
- Lack of necessary information
- Lack of relevant information
- Too much information –
information overload
- Information that is not in a
useful format
- Information that is not
accurate
- Information that is difficult
to produce
- Information that is not
timely to its subsequent use
- Inputs
- Data is not captured
- Data is not captured in time
to be useful
- Data is not accurately
captured – contains errors
- Data is difficult to capture
- Data us captured redundantly
– same data is captured more than once
- Too much data is captured
- Illegal data is captured
- Stored Data
- Data is stored redundantly in
multiple files and/or databases
- Stored data is not accurate
- Data is not secure from
accident or vandalism
- Data is not well organized
- Data is not flexible – not
easy to meet new information needs from stored data
- Data is not accessible
- Economics
- Costs
- Costs are unknown
- Costs are untraceable
- Costs are too high
- Profits
- New markets can be explored
- Current marketing can be
improved
- Control (and Security)
- Too little security or control
- Input data is not adequately
edited
- Crimes (e.g. fraud,
embezzlement) are (or can be) committed against the data
- Ethics are breached on data
or information – refers to data or information getting to unauthorized
people
- Redundantly stored data is
inconsistent in different files or databases
- Data privacy regulations or
guidelines are being (or can be) violated
- Processing errors are
occurring (either by people, machines, or software)
- Decision- making errors are
occurring
- Too much control or security
- Bureaucratic red tape slows
the system
- Controls inconvenience
customers or employees
- Excessive controls cause
processing delays
- Efficiency
- People, machines, or computers waste time
- Data is redundantly input or
copied
- Data is redundantly processed
- Information is redundantly
generated
- People, machines, or computers waste materials and
suppliers
- Effort required for tasks is
excessive
- Materials required for tasks
is excessive
- Service
- The system produces inaccurate results
- The system produces inconsistent results
- The system produces unreliable results
- The system is not easy to learn
- The system is not easy to use
- The system is awkward to use
- The system is inflexible to new or exceptional
situations
- The system is inflexible to change
- The system is incompatible with other systems
- The system is not coordinated with other systems
