457 Javier Pastor Sánchez Life Cycle Cost Estimation Procedure for a Weapon... The LCC estimation procedure establishes that in order to designate a procurement option, the Directorates-General of the State Secretariat shall follow a standardised procedure (not defined), as presented above, which is based on the (generic) PBS, WBS and CBS. These directorates should draw up the PBS, WBS and CBS (for the solution) by adapting the generic standardised structures adopted for this purpose and their level of detail to the operational or functional solution proposed. Instruction 67/2011 is based upon the publication NATO AAP20-PAPS (2010), which constitutes the framework within the NATO Conference of National Armaments Directors used to promote cooperation programmes on the basis of harmonisation of common military needs. It is also the instrument that facilitates decision making at all levels of management. The aim of PAPS is to convert this need into specific requirements, control the deployment of equipment, modernise it and facilitate its withdrawal from service. Unlike 67/2011, NATO-AAP20-PAPS provides terms and definitions for the sake of common understanding. It also creates best practice for processes and offers a common basis for the planning, implementation and control of projects with a focus on mitigating risk. Moreover, NATO-AAP-20-PAPS includes seven supporting reference publications. Four of these address the management of the life cycle, processes and contractual terms. It also lists 23 documents applicable to the content of the instruction, in particular, engineering systems, life cycle processes, standard project management, quality and various AQAP standards. Instruction NATO AAP-48 serves as a guide to the description of life cycle stages, processes and models in a system. In order to dispose of an instrument applicable to a rough estimation procedure for LCC, Spain has transposed the official version of the European standard EN- 60300 into standard UNE-EN-60300-3-3: ‘Dependability management. Life Cycle Costing’, which provides a general introduction to the concept of the cost analysis of this cycle and covers all its applications, although, for now, this standard is little-known and its application is low or non-existent. Of particular note are the costs associated with the dependability of a product and the purpose and value of LCC is explained. In addition, it identifies the characteristic cost elements in order to facilitate the planning of programmes and projects. It affords a general guide to undertaking a LCC analysis, including the development of a cost model, and it divides the cycle up into phases and stages.38 38  AENOR. UNE EN 60300-3-3.
