FCI Change ProcessFCI Change Process

It ain’t over till the paperwork’s done!



• Initiators– CM02: mismatch between design requirements

and other CM elements prompts change to design requirements.

– CM03: mismatch between physical plant and other CM elements prompts change to physical plant.

– CM04: mismatch between elements of facility configuration information prompts change to facility configuration informationALL MISMATCH RESOLUTIONS EXCEPT RESTORE WILL RESULT IN FCI CHANGE



• Initiators– Engineering Change process –

desired/planned update to design requirements– Work Management process – resolution of

discrepancies discovered during work, implementation of authorized changes not directed by EC process

– Corrective Action Process (CAP) – resolution of CM mismatches documented via CAP

– Procedure development process– Informal processes – minor improvements,

trivial problem resolutions, sub-tier processes



• Characteristics of FCI– Defined: content, format, quality is specified,

usually in a procedure– Controlled: revision level, status, storage and

distribution– Tracked: meta-data (index information) exists

in a record system– Owned: mechanism for update exists with

defined responsibilities, including approval authority

– Verifiable



• Initiating Change– Process driver defines need for change– Usually embedded in other process– Process requirement includes record

identification and definition of what in the existing record must be changed or what is the content of a new record.

– Process may initiate a stand-alone FCI process (for example, CAP investigation creates action for Procedure Revision Request)



• Tracking Change– FCI process or initiating process flags FCI

record to identify that a change has been initiated

– Status of FCI record or change record indicates status of development and implementation of revision

– Users of FCI record consider the impact of pending change on the use of FCI (for example, Verify Working Documents)



• Developing Change– FCI change process is defined

• Method• Format• Content• Review

– Impact of change on other FCI is considered– Impact of change on organizations (Change

Management) may be in FCI process or in initiating process



• Scheduling Change– Usually driven by initiating process– Sometimes driven by FCI process– Always driven by resource– Can be established as a restraint

• For Engineering Changes, can be tied to Operations Turnover

• Can be tied to Change Closeout• Another example – Procedure on hold (prevents

use until revision is issued)



Other Issues

• Document Priority– Mechanism to classify documents based on

importance– Used to aid in scheduling changes– Used to aid in determining distribution

• Document Hierarchy– Mechanism to aid in resolving CM mismatches

between documents



Other Issues• Unincorporated Changes

– Long term (or forever) tracking of changes in lieu of incorporation to ensure impact is evaluated

– Used for low priority documents with few likely changes– Risks: error-likely situation, user frustration– Benefits: resource application efficiency

• Training– CM training typically focuses on problem identification

and physical change– Important to include FCI, particularly status control
