System Analysis
- Clockwise cycle
- Fact Finding
- Feasibility Study
- Analysis Phase
- System Design
- Testing
- Implementation
- Documentation
- Evaluation
- Did the system met its objectives? Can it be further improved?
- The new system have to be assessed and suggestions and
feedback form users should be taken into consideration for
further improvements of the system.
- After testing is done successfully
- The new system have to be assessed and suggestions and
feedback form users should be taken into consideration for
further improvements of the system.
- Did the system met its objectives? Can it be further improved?
- User
documentation
- Used to explain to the user how
to use the system. It is presented
as a user guide to the user
- Items
found
- -Screenshots of the user
interface
- -Step by step instructions
on how to launch and
operating the system

- Technical
documentation
- A report to allow users to
alter/upgrade the system in the
future. Troubleshooting can also
be done

- Evaluation
- How the new system
will be implemented
- Direct Implementation
- New system replaces
the old system
entirely
- Users will immediately
enjoy the benefits of the
new system.
- Advantage
- Advantage
- Users unfamiliar with the
new system and will find
difficulties coping the
sudden change.
- New system may have
major errors
- Disadvantages
- Disadvantages
- New system may have
major errors
- Users will immediately
enjoy the benefits of the
new system.
- New system replaces
the old system
entirely
- Phased Implementation
- Parts of old system
slowly replaced by the
new one. It will take a
longer time in order to
make sure every part
works before the next
begun
- System can be tested for
errors before the full
implementation
- Advantage
- Advantage
- Take a longer period of
implementation which
results in the full benefits
being delayed
- Disadvantages
- Disadvantages
- System can be tested for
errors before the full
implementation
- Parts of old system
slowly replaced by the
new one. It will take a
longer time in order to
make sure every part
works before the next
begun
- Parallel running
- New system
implemented alongside
with old system to check
whether it works. If new
systems fails, old system
will be a backup. After all
problems solved, old
system is discarded
- User can fall back on the old
system if new system fails
- Advantages
- Advantages
- Since each job is done
twice, there is more work for
users when both system is
running simulataneously
- Disadvantages
- Disadvantages
- User can fall back on the old
system if new system fails
- New system
implemented alongside
with old system to check
whether it works. If new
systems fails, old system
will be a backup. After all
problems solved, old
system is discarded
- Direct Implementation
- Documentation
- The process of testing is to check
whether the new system functions
works as expected with both
normal usage and potential
problems
- Types of input data
- Normal data
- See if inputing
correct values will
achieved expected
results
- Example
- If question request to input month
- The user will be required to type
in any value range from (1-12)
- such as 4 for the month of April
- such as 4 for the month of April
- The user will be required to type
in any value range from (1-12)
- If question request to input month
- Example
- See if inputing
correct values will
achieved expected
results
- Abnormal data
- Check for
validation and
error-checking
routines
- Example
- If question request to input month
- The user will be required to type any
outside the range or unacceptable
values
- Such as -5 which is not a possible
month number
- Such as -5 which is not a possible
month number
- The user will be required to type any
outside the range or unacceptable
values
- If question request to input month
- Example
- Containing errors
- Check for
validation and
error-checking
routines
- Extreme data
- To make sure validation
works and calculations
cope with a very large or
small number
- Example
- If question request to input month
- The user will be required the
edges of acceptable range such as
the maximum or minimum
- Such as 1 or 12 which is
acceptable as it represents
January and December
- Such as 1 or 12 which is
acceptable as it represents
January and December
- The user will be required the
