A portfolio\u2010of\u2010systems describes the not uncommon situation where an office is responsible for multiple systems in multiple phases of development but those systems are not related by common design, common manufacturing, or necessarily interconnected operationally. The relationship is fundamentally one of management, although other linkages might be present or designed if such additional linkages are deemed beneficial. The portfolio\u2010of\u2010systems concept differs from systems\u2010of\u2010systems and product\u2010line or family\u2010of\u2010systems constructs. This paper describes generalizations of architecting techniques for portfolio situations, particularly recognizing the presence of many largely independent components in multiple stages of development with an ongoing or episodic process. The paper presents two case studies of actual portfolios: One a portfolio of operational demonstration systems and the other a portfolio of weather satellites.<\/jats:p>","DOI":"10.1002\/sys.21486","type":"journal-article","created":{"date-parts":[[2019,4,18]],"date-time":"2019-04-18T04:02:16Z","timestamp":1555560136000},"page":"335-347","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Architecting a portfolio of systems"],"prefix":"10.1002","volume":"22","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-7465-2189","authenticated-orcid":false,"given":"Mark W.","family":"Maier","sequence":"first","affiliation":[{"name":"The Aerospace Corporation INCOSE Fellow Chantilly Virginia"}]}],"member":"311","published-online":{"date-parts":[[2019,4,17]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1520-6858(1998)1:4<267::AID-SYS3>3.0.CO;2-D"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/9781119173670"},{"key":"e_1_2_6_4_1","volume-title":"Architecting Principles for Systems\u2010of\u2010Systems","author":"Maier MW"},{"issue":"4","key":"e_1_2_6_5_1","first-page":"325","article-title":"On the systems engineering and management of systems of systems and federations of systems","volume":"2","author":"Sage AP","year":"2001","journal-title":"Infor Knowl Syst Manage"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/sys.21302"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/3-540-28901-1"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s001630100002"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/sys.20039"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1109\/MS.2004.1293069"},{"key":"e_1_2_6_11_1","volume-title":"Architecting Automotive Product Lines: Industrial Practice","author":"Gustavsson H","year":"2010"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1109\/MS.2003.1241367"},{"key":"e_1_2_6_13_1","doi-asserted-by":"crossref","unstructured":"MartinJN.Overview of an Emerging Standard on Architecture Processes\u2014ISO\/IEC\/IEEE 42020. 2018 IEEE International Systems Conference (SysCon) Vancouver Canada:IEEE; 23\u201026 April 2018.","DOI":"10.1109\/SYSCON.2018.8369544"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.2307\/258557"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.2307\/258920"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.5465\/amj.2007.24160888"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.2307\/259349"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.5465\/amle.2003.10932145"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1201\/9781420079142"},{"key":"e_1_2_6_20_1","volume-title":"System Architecture: Strategy and Product Development for Complex Systems","author":"Crawley E","year":"2015"},{"key":"e_1_2_6_21_1","volume-title":"DOD Architecture Framework 2.0: A Guide to Applying Systems Engineering to Develop Integrated, Executable Architectures","author":"Dam SH","year":"2015"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.compind.2015.06.010"},{"key":"e_1_2_6_23_1","first-page":"1","article-title":"The framework for enterprise architecture: background, description and utility","author":"Zachman JA","year":"1996","journal-title":"Zachman Intl"},{"key":"e_1_2_6_24_1","doi-asserted-by":"crossref","unstructured":"EmeryD HilliardR.Every Architecture Description Needs a Framework: Expressing Architecture Frameworks Using ISO\/IEC 42010.
