One effective way of managing such tasks is to decompose them into groups. However, not all tasks are decomposable. Without the need to apply a decomposition method, this paper describes a simple, quantitative approach to test whether an underlying pattern of relationships exists between interdependent project tasks, such that they may be rearranged into groups. In addition, a grouping efficiency index is introduced to predict how good the best possible decomposition is. The proposed approach and the grouping index are applied to simple hypothetical projects and a sample project adapted from the literature. Both the approach and the grouping index are proved to be powerful yet very easy to use.<\/jats:p>","DOI":"10.1177\/1063293x09102248","type":"journal-article","created":{"date-parts":[[2009,2,25]],"date-time":"2009-02-25T10:28:10Z","timestamp":1235557690000},"page":"35-42","source":"Crossref","is-referenced-by-count":6,"title":["An Eigenvalue Based Approach for Assessing the Decomposability of Interdependent Design Project Tasks"],"prefix":"10.1177","volume":"17","author":[{"given":"Hamdi A.","family":"Bashir","sequence":"first","affiliation":[{"name":"Department of Mechanical and Industrial Engineering,\rSultan Qaboos University,"}]},{"given":"Khalid","family":"AlZebdeh","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Industrial Engineering,\rSultan Qaboos University"}]},{"given":"Jamil","family":"Abdo","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Industrial Engineering,\rSultan Qaboos University"}]}],"member":"179","published-online":{"date-parts":[[2009,3,1]]},"reference":[{"key":"atypb1","volume-title":"Project Management for Business and Engineering","author":"Nicholas, J.","year":"2004"},{"issue":"6","key":"atypb2","first-page":"23","volume":"32","author":"Creese, R.C.","year":"1991","journal-title":"Cost Engineering"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1109\/TEM.1981.6448589"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1109\/17.946528"},{"key":"atypb5","volume-title":"A Knowledge-Based Tool for Multilevel Decomposition of a Complex Design Problem, NASA TP-2903","author":"Rogers, J.L.","year":"1989"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1080\/00207549308956755"},{"key":"atypb7","volume-title":"Multidisciplinary Design Optimization: An Emerging New Engineering Discipline, NASA Technical Memorandum 107761","author":"Sobieszczanski-Sobieski, J.","year":"1993"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1007\/BF01588087"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.43.3.276"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.43.8.1104"},{"key":"atypb11","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-8352(02)00230-9"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-8352(03)00031-7"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1177\/106329303034503"},{"key":"atypb14","doi-asserted-by":"publisher","DOI":"10.1109\/TEM.2005.850722"},{"key":"atypb15","doi-asserted-by":"publisher","DOI":"10.1177\/1063293X06072483"},{"key":"atypb16","volume-title":"The Analytic Hierarchy Process","author":"Saaty, T.L.","year":"1980"},{"key":"atypb17","volume-title":"Proceedings of the 1987 International Conference on Engineering Design","author":"Wallace, K.M."},{"key":"atypb18","doi-asserted-by":"publisher","DOI":"10.1016\/j.bushor.2004.10.013"},{"key":"atypb19","doi-asserted-by":"publisher","DOI":"10.1016\/S0263-7863(03)00058-9"},{"key":"atypb20","doi-asserted-by":"publisher","DOI":"10.1017\/S0890060499133055"},{"key":"atypb21","volume-title":"Controlling Software Projects","author":"DeMarco, T.","year":"1982"},{"key":"atypb22","doi-asserted-by":"publisher","DOI":"10.1016\/S0142-694X(98)00024-6"},{"key":"atypb23","doi-asserted-by":"publisher","DOI":"10.1177\/001316446002000116"},{"key":"atypb24","volume-title":"Applied Factor Analysis","author":"Rummel, R.J.","year":"1988"},{"key":"atypb25","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpe.2005.01.014"},{"key":"atypb26","doi-asserted-by":"publisher","DOI":"10.1016\/j.cie.2004.06.008"}],"container-title":["Concurrent Engineering"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1063293X09102248","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1063293X09102248","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T14:48:17Z","timestamp":1777387697000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1063293X09102248"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,3]]},"references-count":26,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2009,3]]}},"alternative-id":["10.1177\/1063293X09102248"],"URL":"https:\/\/doi.org\/10.1177\/1063293x09102248","relation":{},"ISSN":["1063-293X","1531-2003"],"issn-type":[{"value":"1063-293X","type":"print"},{"value":"1531-2003","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,3]]}}}
