A model is presented that integrates different perspectives and stages serving as an aid for the analysis of business models and focused positioning of IT-products. Four generic business models are analysed with regard to the product management function in general and the positioning field for IT-products specifically: off-the-shelf (license), license plus service, project, and system service (incl. cloud computing).},

  abstract  = {In der betrieblichen Entwicklungspraxis klaffen Anspruch und Realit{\"a}t bei der Gestaltung betrieblicher Softwareentwicklungsprozesse auseinander. Nicht selten werden „Vorgehensmodelle"definiert, jedoch nicht konsequent oder nicht mit dem erw{\"u}nschten Erfolg eingesetzt. Die Modellierung der Entwicklungsabl{\"a}ufe garantiert nicht deren effektive und effiziente Umsetzung; dazu ist ein „Prozeßmanagement"erforderlich. Die verf{\"u}gbaren Prozeßmanagementans{\"a}tze eignen sich f{\"u}r unterschiedliche Anwendungsfelder und Organisationskulturen, sind dementsprechend auch auf die Softwareentwicklung {\"u}bertragbar, adressieren jedoch nur bedingt den zentralen Erfolgsfaktor betrieblicher Softwareentwicklung: die Zufriedenheit der Anwender als Kunden der Softwareentwicklung. Der Schl{\"u}ssel f{\"u}r erfolgreiche Softwareentwicklungsprozesse liegt nicht im Prozeßmanagement allein, sondern in dessen Ausgestaltung mit Blick auf den Kunden. Ansatzpunkte f{\"u}r ein kundenorientiertes Softwareprozeßmanagement sind die Etablierung einer Kunden/Lieferantenbeziehung, die Fokussierung und Differenzierung der Entwicklungsprozesse, die Benutzerinvolvierung, Simultaneous Engineering und die gezielte Identifikation, Integration und Kooperation der „Stimme des Kunden"und der „Stimme des Ingenieurs". Die Bewertung kundenorientierter Softwareprozesse wird diskutiert und Schlußfolgerungen f{\"u}r Forschung und Praxis skizziert.},
