Subject: Comments on Public View of Task DEX
Comments by Gordon Robb - LSC Group 1. Introduction Reference: - information required for through life configuration change management of a product and its support solution. This should be changed to just Configuration Management. The subject matter of Task deals with the overall CM of the product and not just CCM. 2. Related DEXs The information exchanged by the Task Specification DEX is normally between a product developer and a customer/end-user. It is assumed that each party has access to the Product information including breakdowns, equipments, components, effectivities etc. The Product Information should be changed to the correct terminology of Product Configuration Information. DEX (D001):- Product Breakdown for Support. This DEX can be used to specify the as designed product structure of an aircraft, including configuration effectivities. It will incorporate a breakdown structure detailing what parts can be fitted into which positions on the aircraft. * I would have expected this cross-reference to DEX1 to read exactly the same as the Avn Mnt DEX viz DEX (D001):- Product Breakdown for Support. This DEX can be used to specify the as designed product structure of an aircraft. It will incorporate a breakdown structure detailing what components can be fitted into which positions on the aircraft; * The 'configuration effectivities' is basically incorrect - the DEX does not use the "Configuration Effectivity" module but a series of 'effectivity' templates * Why isn't the DEX using DEX 8? There will be occasions where the 'product' is in-service and requires additional Tasks. 3. Scope Identification of the product (supported item), to which the task applies. The Avn Mnt DEX uses "Reporting the authorisation to undertake a maintenance task on a reportable item (an asset)" This diversion from 'standardized PLCS jargon' between the 2 OASIS PLCS DEXs COULD be confusing for new 'players'. This Task DEX uses PIF [Product in Focus] throughout. Could this be resolved to a 'PIF' statement in both DEXs? 4 ISO 10303-239 Activity model definitions Identify potential task * 2nd bullet - configuration change management tasks to be undertaken by support participants such as fitting a local modification or conducting an audit of product configuration; * This statement seems very confusing. The subject matter should be Configuration Management not CCM. * What is a 'local modification' * What is 'an audit of product configuration' The statement should be corrected to read "Configuration Management tasks to be undertaken by support participants such as modification implementations or conducting a physical configuration audit of the product'. 5. Detailed Information Requirements Product in focus identification * Identification of the product in focus to which the task specification applies. Identification of the product in focus includes the progression codes such as revision numbers. What are progression codes? 6. Information Requirements Overview * Task effectivity / applicability * The validity of a task, or part thereof, may be constrained to a specific context. These constraints are referred to as effectivity or applicability Why a 'or' when the rest of the script uses '/' and (_) and in reality why mention applicability at all when no reference is placed on its usage. ________________________________ DISCLAIMER: ***SECURITY LABEL: NOT PROTECTIVELY MARKED*** The information in this message is confidential and may be legally privileged.
