Proposed Permitted Actions on various entities and attributes

Create New Items · Change Control not required
· With ‘Lite’ change control
· No new items to be introduced without Full Configuration Management
Change Functional attribute values · No Restriction – Under responsible engineer’s control
· Varies – ‘lite’ could imply some attribute changes allowed
· No attribute changes allowed.
· May imply new part required for new fit, form or function change when in these states.
· See when to Change a Part Number (section 6.14)
Change Business Attributes · Change Control not required
· Without Change control
· Varies - some attributes in some companies require full change control for some non-engineering attributes.
· E. G. Make/Buy flags and supplier changes require some kind of change control in some companies.
BOM Creation · Change Control not required
· Lite change control at project teams discretion.
· No new BOM to be introduced without change control
· Items in ‘service only’ and ‘obsolete’ states cannot be used on BOM’s with a lesser state

Other Information

LCM Terms · None
· Ramp – Up

Notes:

The above chart was adapted from EIA/IS 649. The life cycle state names used are not universal. Therefore provision needs to be made in PLM systems to use aliases so the user can map their terms to the system’s internal state names.
