3 Terms and definitions For the purposes of this document, the terms and definitions given in ISO/IEC/IEEE 12207, ISO/IEC/IEEE 15288, and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: — ISO Online browsing platform: available at https://www.iso .org/obp — IEC Electropedia: available at http://www.electropedia .org/ NOTE 1 For additional terms and definitions in the field of systems and software engineering, see ISO/IEC/IEEE 24765, which is published periodically as a “snapshot ” of the SEVOCAB (Systems and software engineering – Vocabulary) database and is publicly accessible at www.computer.org/sevocab. NOTE 2 Because feature-based PLE is a specialization of the more general product line engineering approach described in ISO/IEC 26550, some of the terminology used herein is noted as a specialization of the terminology from ISO/IEC 26550, with further details provided in Annex A . 3.1 bill-of-features specification for a member product (3.8) in the product line (3.16), rendered in terms of the specific features (3.4) from the feature catalogue (3.5) that are chosen for that member product 3.2 bill-of-features portfolio collection comprising the bill-of-features (3.1) for each member product (3.8) in a product line (3.16) 3.3 domain supersets collection comprising the feature catalogue ( 3.5 ) and shared asset supersets (3.18) 3.4 feature characteristic of a member product (3.8) in a product line (3.16) that distinguishes it from other member products in the product line Note 1 to entry: Features can a) express the customer-visible or end-user-visible variability among the member products in a product line, or b) distinguish implementation variability not directly visible to a customer or end user except through non-functional differences such as price, performance, noise, weight, energy and more.
4.1 General This clause gives a brief informational overview of feature-based product line engineering, as a way of introducing key concepts that are important for understanding the purpose and content of this document. Software and systems product line engineering emerged some time ago as way to engineer a portfolio of related products in an efficient manner, taking full advantage of the products ’ similarities while respecting and managing their differences. Here “engineer ” means all of the activities involved in planning, producing, delivering, deploying, sustaining, and retiring products. Born in the software engineering field in the 1970s and 1980s and based largely on the concept of software reuse, PLE has long been known for delivering significant improvements in development time, cost, and quality of products in a product line .
