However, there are few systematic studies that examine whether graphical models are more effective than other representation (such as textual descriptions). Process models provide an abstract graphical view of organizational procedures by reducing the complex reality of the work performed by a company to its most important activities. Such models are useful to train new employees, to document and allow improving organizational procedures and policies. This paper describes an experiment to address if there are significant differences in terms of process understand ability depending on whether textual work instructions or process models are used to represent a business process. We compared a control group of subjects that received textual work instructions to a second group, which received process models, in terms of their ability to understand the process. We found empirical support that using textual work instructions or process models do not influence process understand ability for non-expert users but do influence for experienced users.","linkCode":null,"source":{"__ref":"Source:23151"},"sourceInstance":{"__ref":"SourceInstance:3112"},"authors":[{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:20574"},"affiliations":[{"__ref":"Affiliation:241"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:33300"},"affiliations":[{"__ref":"Affiliation:241"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:7359"},"affiliations":[{"__ref":"Affiliation:241"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:3979"},"affiliations":[{"__ref":"Affiliation:241"},{"__ref":"Affiliation:6"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:22223"},"affiliations":[{"__ref":"Affiliation:1577"}]}]},"Source:91":{"__typename":"Source","id":"91","longName":"ACM International Conference on Information and Knowledge Management","shortName":"CIKM","type":"CONFERENCE"},"SourceInstance:3145":{"__typename":"SourceInstance","id":"3145","name":"CIKM 2015"},"Author:40019":{"__typename":"Author","id":"40019","ibmer":null},"AuthorName:33366":{"__typename":"AuthorName","id":"33366","firstName":"Daniel Lemes","firstNameInitials":"D.L.","lastName":"Gribel","author":{"__ref":"Author:40019"}},"Affiliation:205":{"__typename":"Affiliation","id":"205","isIbm":false},"Author:14935":{"__typename":"Author","id":"14935","ibmer":null},"AuthorName:11057":{"__typename":"AuthorName","id":"11057","firstName":"Maira Gatti","firstNameInitials":"M.G.","lastName":"de Bayser","author":{"__ref":"Author:14935"}},"Publication:14136":{"__typename":"Publication","id":"14136","slug":"a-clustering-based-approach-to-detect-probable-outcomes-of-lawsuits","title":"A clustering-based approach to detect probable outcomes of lawsuits","type":{"__typename":"PublicationType","displayValue":"Conference paper"},"published":"2015-10-17","publishedMeta":{"__typename":"PublishedMeta","source":"CIKM 2015","year":"2015"},"abstract":"The numerous lawsuits in progress or already judged by the Brazilian Supreme Court consists of a large amount of non-structured data. This leads to a large number of hidden or unknown information, since some relationships between lawsuits are not explicit in the available data; and contributes to generate non-intuitive influences between variables, which in addition increases the degree of uncertainty on judicial outcomes. This work proposes an approach to identify possible judgment outcomes that considers the use of similarity calculations and clustering mechanisms based on lawsuits patterns. The similarity problem was tackled by analysing metadata manually extracted from lawsuits; and this work also presents an approach to detect clusters and to compile past votes. From the results, it is possible to verify lawsuits most likely outcomes and to detect their degree of uncertainty.","linkCode":null,"source":{"__ref":"Source:91"},"sourceInstance":{"__ref":"SourceInstance:3145"},"authors":[{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:33366"},"affiliations":[{"__ref":"Affiliation:205"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:11057"},"affiliations":[{"__ref":"Affiliation:6"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:3979"},"affiliations":[{"__ref":"Affiliation:6"}]}]},"Source:23210":{"__typename":"Source","id":"23210","longName":"International Workshop on Product Line Approaches in Software Engineering","shortName":"PLEASE","type":"CONFERENCE"},"SourceInstance:3226":{"__typename":"SourceInstance","id":"3226","name":"PLEASE 2015"},"Ibmer:1618":{"__typename":"Ibmer","id":"1618","slug":"vinicius-segura","displayName":"Vinícius Segura"},"Author:54216":{"__typename":"Author","id":"54216","ibmer":{"__ref":"Ibmer:1618"}},"AuthorName:2244":{"__typename":"AuthorName","id":"2244","firstName":"Vinícius","firstNameInitials":"V.","lastName":"Segura","author":{"__ref":"Author:54216"}},"Ibmer:2588":{"__typename":"Ibmer","id":"2588","slug":"leonardo-pondian-tizzei","displayName":"Leonardo Pondian Tizzei"},"Author:1385":{"__typename":"Author","id":"1385","ibmer":{"__ref":"Ibmer:2588"}},"AuthorName:3949":{"__typename":"AuthorName","id":"3949","firstName":"Leonardo P.","firstNameInitials":"L.P.","lastName":"Tizzei","author":{"__ref":"Author:1385"}},"Author:40284":{"__typename":"Author","id":"40284","ibmer":null},"AuthorName:33636":{"__typename":"AuthorName","id":"33636","firstName":"Joao Paulo De F.","firstNameInitials":"J.P.D.F.","lastName":"Ramirez","author":{"__ref":"Author:40284"}},"Author:40285":{"__typename":"Author","id":"40285","ibmer":null},"AuthorName:33637":{"__typename":"AuthorName","id":"33637","firstName":"Marcelo N.

Before the widespread use of web services, most software with a clear goal were delivered as packages that users installed on their own system. New versions were delivered with a much lower frequency, with periods in between versions ranging from months to years. Development cycles were divided into large design, coding and testing phases culminating in the release of a new stable version. In software development in the context of applied science, even when the goal is clear, the process to attain it is not. Hence, working releases that capture the current software state must be released frequently in order to reduce the risks for all stakeholders and to make it possible to assess the current state of a project and steer it in the right direction. This paper explores the usefulness of DevOps concepts to improve the development of software that supports scientific projects. We establish the similarities and differences between scientific projects and web applications development, and discuss where the related methodologies need to be extended. Unique challenges are discussed herewith developed solutions, and still open questions. Lessons learned are highlighted as best practices to be followed in research projects. This discussion is rooted in our experience in real-life projects at the IBM Research Brazil Lab, which just as well apply to other research institutions.","linkCode":null,"source":{"__ref":"Source:21904"},"sourceInstance":{"__ref":"SourceInstance:3258"},"authors":[{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:3152"},"affiliations":[{"__ref":"Affiliation:6"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:3979"},"affiliations":[{"__ref":"Affiliation:6"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:947"},"affiliations":[{"__ref":"Affiliation:6"}]}]},"Source:356":{"__typename":"Source","id":"356","longName":"Annual ACM Symposium on Applied Computing","shortName":"SAC","type":"CONFERENCE"},"SourceInstance:3317":{"__typename":"SourceInstance","id":"3317","name":"SAC 2015"},"Publication:14671":{"__typename":"Publication","id":"14671","slug":"architecting-cloud-tools-using-software-product-line-techniques-an-exploratory-study","title":"Architecting cloud tools using software product line techniques: An exploratory study","type":{"__typename":"PublicationType","displayValue":"Conference paper"},"published":"2015-04-13","publishedMeta":{"__typename":"PublishedMeta","source":"SAC 2015","year":"2015"},"abstract":"Multitenant cloud computing tools are usually complex and have to manage variabilities to support customization. Software Product Line (SPL) techniques have been successfully applied in the industry to manage variability in complex systems. However, few works in the literature discuss the application of SPL techniques to architect industry cloud computing tools, resulting in a lack of support to cloud architects on how to apply such techniques. This work presents how software product line techniques can be applied for architecting cloud tools, and discusses the benefits, drawbacks, and some challenges of applying such techniques to develop a real industry cloud tool, named as Installation Service.","linkCode":null,"source":{"__ref":"Source:356"},"sourceInstance":{"__ref":"SourceInstance:3317"},"authors":[{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:3949"},"affiliations":[{"__ref":"Affiliation:6"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:3979"},"affiliations":[{"__ref":"Affiliation:6"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:3152"},"affiliations":[{"__ref":"Affiliation:6"}]},{"__typename":"PublicationHasAuthorName","authorName":{"__ref":"AuthorName:947"},"affiliations":[{"__ref":"Affiliation:6"}]}]},"ROOT_QUERY":{"__typename":"Query","blogPostsSearch({\"filterBy\":{\"ibmerSlug\":\"leonardo-guerreiro-azevedo\"},\"limit\":4,\"start\":0})":{"__typename":"BlogPostsSearchConnection","nodes":[],"totalCount":0},"ibmersBySlug({\"slugs\":[\"leonardo-guerreiro-azevedo\"]})":[{"__ref":"Ibmer:2024"}],"patents({\"after\":\"-1\",\"filterBy\":{\"ibmerSlug\":\"leonardo-guerreiro-azevedo\"},\"first\":10,\"sortBy\":{\"direction\":\"DESC\",\"option\":\"DATE\"}})":{"__typename":"QueryPatents_Connection","nodes":[{"__typename":"Patent","num":"11989628","title":"MACHINE TEACHING COMPLEX CONCEPTS ASSISTED BY COMPUTER VISION AND KNOWLEDGE REASONING","country":"US","date":"2024-05-20"},{"__typename":"Patent","num":"11048877","title":"SYSTEM AND METHOD FOR GENERATING ONTOLOGIES USING NATURAL LANGUAGE UTTERANCES","country":"US","date":"2021-06-28"},{"__typename":"Patent","num":"10958531","title":"ON-DEMAND REMOTE PREDICTIVE MONITORING FOR INDUSTRIAL EQUIPMENT ANALYSIS AND COST FORECAST","country":"US","date":"2021-03-22"}],"totalCount":3},"publications({\"after\":\"39\",\"filterBy\":{\"ibmerSlug\":\"leonardo-guerreiro-azevedo\"},\"first\":10,\"sortBy\":\"NEWEST\"})":{"__typename":"QueryPublications_Connection","totalCount":45,"nodes":[{"__ref":"Publication:14075"},{"__ref":"Publication:14136"},{"__ref":"Publication:14382"},{"__ref":"Publication:14491"},{"__ref":"Publication:14671"}]}}},"ssrDateString":"2025-03-01T19:34:50.420Z"},"__N_SSP":true},"page":"/people/[personSlug]","query":{"publications-page":"5","personSlug":"leonardo-guerreiro-azevedo"},"buildId":"v9TvvervEOiCcTzEPxR9P","isFallback":false,"gssp":true,"locale":"en-US","locales":["en-US"],"defaultLocale":"en-US","scriptLoader":[]}</script></body></html>
