CAB - Change Advisory Board
4 of:
* Assessing any potential IT changes (main one)
* Manage quality standards
* Change requests and prioritise requests when necessary
* Review any impact on security or compliance with legislation etc.

Fill The Blank:
After planning, the digital change is …………………. and …………………….. while also testing the is working as intended and it does not impact other ………………..
CAB - Change Advisory Board
Implemented, Documented, Processes
Explain:
Briefly, Standard Technical Change Management
Known changes to services and/or IT system infrastructure with low risks and impacts on business; pre-approved by senior management
Explain:
Briefly, Normal Technical Change Management
Changes that have to be approved prior to being carried out with high risk and must be approved via CAB - may have an impact on the business’ ability to function
Explain:
Briefly, Emergency Technical Change Management
Critical changes that must be carried out as a matter of urgency - cannot be planned for
Fill The Blank:
Identify the intended changes and the …………… behind the changes as well as ……. and anticipated timescales
Identifying the changes to be made
Reasons, Risks
Fill The Blanks:
The risks involved must be communicated ………….. and timely to all relevant ………………..
Identifying, communicating potent. risks, wanted impacts to stakeholders
Positively, Stakeholders
Fill The Blank:
All stakeholders must be ……………….. any changes will not cause too much ………………. to them.
Identifying, communicating potent. risks, wanted impacts to stakeholders
Confident, Disruption
Fill The Blank:
Any planning of changes must be ……………….. so people carrying out changes can implement them in the correct ……….. using the correct ……………….. etc.
Configuration of the new system and process
Documented, Order, Equipment
Fill The Blank:
All changes must be …………… to ensure that systems and processes work as ………………..
Configuration of the new system and process
Tested, Intended
Explain:
Briefly, direct changeover
Methods of implementing change
Major change launched all at once as opposed to more conservative approaches
State:
2 advantages of direct changeover
Methods of implementing change
- Low cost/Cheap
- Only one system running at a time
State:
2 disadvantages of direct changeover
Methods of implementing change
2 of:
* Staff require training or may be slow to pickup the system at first without training
* Data can be lost permanently
* Difficult to plan
Explain:
Briefly, Parallel changeover
Methods of implementing change
Old and new system run simulatenously until new system is ready to be fully adopted
State:
2 advantages of parallel changeover
Methods of implementing change
- Staff will be less overwhelmed by being given time to adjust
- If new system fails, old one still available
State:
1 disadvantage of parallel changeover
Methods of implementing change
Costly; have to pay for both to run + staff
Explain:
Briefly, Pilot changeover
Methods of implementing change
Testing a new system within a department or office before fully rolling it out to the whole company
State:
2 advantages of pilot changeover
Methods of implementing change
- System will be working correctly when rolled out to all users
- Allows for continuing development/changes, based off feedback
State:
2 disadvantages of pilot changeover
Methods of implementing change
- Takes a lot of time to be carried out
- Partaking in changeover pilot (the department/region) risks loss of data
Explain:
Briefly, Phased changeover
Methods of implementing change
Change from old to new system in stages to ensure all necessary fixes can be made during the changeover
State:
2 advantages of phased changeover
Methods of implementing change
- Staff can be trained gradually with only current part of system
- Easier to find system errors
State:
2 disadvantages of phased changeover
Methods of implementing change
- More expensive than direct changeover as you have to test each phase seperately
- Takes a long time to implement whole system
