5 HAW Hamburg, CARPE 2011, Prof. Dr. Rüdiger Weißbach, Revision : 01.11.2011- 5 - Leading Questions How are users involved in the Requirements Engineering and Management (RE&M) Process? Requirements Elicitation Requirements Analysis Requirements Documentation Requirements Validation Requirements Management Einführung Allgemeine betriebs- wirtschaftliche Aspekte Informationssysteme und Marketing Entwicklung von Informations- systemen IT und allgemeines Management Betrieb von Infor- mationssystemen

6 HAW Hamburg, CARPE 2011, Prof. Dr. Rüdiger Weißbach, Revision : 01.11.2011- 6 - Leading Questions How are users involved in the Requirements Engineering and Management (RE&M) Process? Requirements Elicitation Requirements Analysis Requirements Documentation Requirements Validation Requirements Management Einführung Allgemeine betriebs- wirtschaftliche Aspekte Informationssysteme und Marketing Entwicklung von Informations- systemen IT und allgemeines Management Betrieb von Infor- mationssystemen … analyzing instruction books, the users tend to have a more passive function,

7 HAW Hamburg, CARPE 2011, Prof. Dr. Rüdiger Weißbach, Revision : 01.11.2011- 7 - Users Communication in the RE&M Process … how instruction books assume Einführung Allgemeine betriebs- wirtschaftliche Aspekte Informationssysteme und Marketing Entwicklung von Informations- systemen IT und allgemeines Management Betrieb von Infor- mationssystemen REngineerDeveloper writes down req. RE asks for requirements Users answer asks for acknowledgement Users acknowledge RE forwards req.

8 HAW Hamburg, CARPE 2011, Prof. Dr. Rüdiger Weißbach, Revision : 01.11.2011- 8 - Users Einführung Allgemeine betriebs- wirtschaftliche Aspekte Informationssysteme und Marketing Entwicklung von Informations- systemen IT und allgemeines Management Betrieb von Infor- mationssystemen REngineerDeveloper writes down req. RE asks for requirements Users answer asks for acknowledgement Users acknowledge RE forwards req. Communication in the RE&M Process … how instruction books assume 2-step heavyweight communication flow

9 HAW Hamburg, CARPE 2011, Prof. Dr. Rüdiger Weißbach, Revision : 01.11.2011- 9 - Users Einführung Allgemeine betriebs- wirtschaftliche Aspekte Informationssysteme und Marketing Entwicklung von Informations- systemen IT und allgemeines Management Betrieb von Infor- mationssystemen REngineerDeveloper writes down req. RE asks for requirements Users answer asks for acknowledgement Users acknowledge RE forwards req. Communication in the RE&M Process … how instruction books assume 2-step heavyweight communication flow Problems: Different terminologies and communication cultures between users and software engineers Experts are not able to clarify tacit knowledge Experienced users are not able to keep an analytical distance to their requests Users are not trained in modeling languages Software engineers don't have (enough) domain knowledge No experienced requirements engineer to moderate the process

10 HAW Hamburg, CARPE 2011, Prof. Dr. Rüdiger Weißbach, Revision : 01.11.2011- 10 - Users Einführung Allgemeine betriebs- wirtschaftliche Aspekte Informationssysteme und Marketing Entwicklung von Informations- systemen IT und allgemeines Management Betrieb von Infor- mationssystemen REngineerDeveloper writes down req. RE asks for requirements Users answer asks for acknowledgement Users acknowledge RE forwards req. Communication in the RE&M Process … how instruction books assume Special Case Agile Development Problems: Different terminologies and communication cultures between user representatives and software engineers Users are not trained in modeling languages Experts are not able to clarify and tacit knowledge Experienced users are not able to keep an analytical distance to their requests Software engineers don't have (enough) domain knowledge No experienced requirements engineer to moderate the process Special Case Agile Development: agile processes institutionalize a close communication cycle between users and developers (e.g. the on site customer)

11 HAW Hamburg, CARPE 2011, Prof. Dr. Rüdiger Weißbach, Revision : 01.11.2011- 11 - Einführung Allgemeine betriebs- wirtschaftliche Aspekte Informationssysteme und Marketing Entwicklung von Informations- systemen IT und allgemeines Management Betrieb von Infor- mationssystemen Communication in the RE&M Process … and how reality is different The FaPrAa Project FaPrAa: Fachabteilungen im Prozess der Anforderungsanalyse (= Business Departments and the Requirements Engineering Process in IT Projects) research project at the Hamburg UAS (2009ff) 25 semi-structured interviews in SME in northwestern Germany (interviewees work in IT and business departments [BD]), focus on business applications (not on technical software)

12 HAW Hamburg, CARPE 2011, Prof. Dr. Rüdiger Weißbach, Revision : 01.11.2011- 12 - Einführung Allgemeine betriebs- wirtschaftliche Aspekte Informationssysteme und Marketing Entwicklung von Informations- systemen IT und allgemeines Management Betrieb von Infor- mationssystemen Communication in the RE&M Process … and how reality is different The FaPrAa Project – some intermediate results line management has to manage its own work and own processes => users often have documented own ideas users in traditional business often have experience in process organisation only few companies are using a formalised process model, some companies are working quasi agile, none of the interviewed companies has established an explicit role of a requirements engineer

13 HAW Hamburg, CARPE 2011, Prof. Dr. Rüdiger Weißbach, Revision : 01.11.2011- 13 - Einführung Allgemeine betriebs- wirtschaftliche Aspekte Informationssysteme und Marketing Entwicklung von Informations- systemen IT und allgemeines Management Betrieb von Infor- mationssystemen Communication in the RE&M Process … and how reality is different The FaPrAa Project – some intermediate results different cultures: 1.long term employed IT workers with domain and application knowledge are knowing the right things to do 2.long term co-operation between IT workers and BD managers, improving and upgrading existing systems 3.BD managers are promoting new applications, IT staff is only responsible for running infrastructure 4.top management decides about the introduction of new systems with external process support (consultnts, proj.mangrs)
