Methoden der Programm-Entwicklung kennt man seitdem es Computer gibt. Auf- grund der Veranderung der Leistungen, die auf dem Computer bewaltigt werden koennen, verschieben sich ebenfalls seit dieser Zeit die Ziele der Programmierung. Wahrend es in der Anfangsphase mehr darauf ankam, moeglichst viele Maschinen- befehle auf dem verfugbaren kleinen Speicherplatz darzustellen, ging es in den 50er und 60er Jahren primar darum, moeglichst schnelle und effektive Programme zu entwickeln, wobei der Schwerpunkt sowohl auf der Geschwindigkeit als auch auf der Speicherknappheit lag. Heute durften die wesentlichen Ziele darin beste- hen, Programme so zu entwickeln, dass sie moeglichst computerunabhangig und anderungsfreundlich sind. Diesem Wandel ist auch die Bezeichnung der Programm-Entwicklung gefolgt. Heu- te wird kaum noch von Programmierung oder Software-Entwicklung gesprochen, sondern es wird nur noch Software-Engineering betrieben, um zu verdeutlichen, dass zur Entwicklung von Programmen eine gewisse Methodik und Systematik vor- liegen muss, da Erfahrungen gezeigt haben, dass man bei Anwendung dieser Metho- dik auch bei individuellen Fragestellungen robuste und kostengunstige Programme erhalt.

Das vorliegende Buch ist aus Vorlesungen entstanden, die im Rahmen der Marketing-Ausbildung an der Universitat Karlsruhe gehalten wurden. Zusatz- lich zu dem in diesem Buch behandelten Stoff iiber Computergestiitztes Marketing umfaBt das Lehrprogramm fiir diesen Teilbereich des Marketing an der Universitat Karlsruhe z. B. Rechnerpraktika, in denen der Umgang mit auf unterschiedlichen Computern implementierten Entscheidungsunterstiit- zungswerkzeugen fiir das Marketing geiibt werden kann (hierzu entsteht momen- tan ein Buch mit Diskette, das eine Briickenfun: ktion zwischen den Einsatzmoglich- keiten von quantitativen Ansatzen und Modellen und ihrer Umsetzung auf dem Computer erfiillen solI), sowie Vorlesungen, Ubungen und Seminare, in denen an- dere Einzelbereiche des Marketing, wie z. B. Internationales Marketing oder Konsumentenverhalten oder Marketing-Planung oder Marktforschung vertieft werden konnen. Dabei wird immer auch Wert darauf gelegt, daB auch das fiir die Modellbildung und Methodenanwendung im Marketing benotigte Hin- tergrundwissen beherrscht wird. Angesichts der stoffiichen Fiille und VielGBPalt der heute moglichen Marketing- Ausbildung wendet sich das vorliegende Buch einerseits an Dozenten und Stu- denten, die sich im Rahmen des Lehrprogramms ihrer Hochschule mit Fra- gestellungen der computergestiitzten Entscheidungsunterstiitzung im Marketing beschaftigen wollen, sowie andererseits an den interessierten "Marketing-Ma- nager aus der Praxis", der sich einen aktuellen Uberblick iiber historische Entwicklungen, den augenblicklichen Stand und Zukunftsperspektiven des com- putergestiitzten Marketing verschaffen will. Die Gliederung des Buches ist so angelegt, daB sie einen raschen Einstieg in den dargebotenen Stoff auch bei unterschiedlichen Zielsetzungen von potentiellen Le- sem erleichtert.

Das vorliegende Buch stellt ein integriertes System zum operativen Controlling des Datenverarbeitungsbereiches in der Unternehmung vor. Controlling der ADV als Schaffung eines abgestimmten Planungs- und Kontrollsystems muA eine wirtschaftliche, flexible und sichere Datenverarbeitung, mit der auch die Benutzer zufrieden sind, gewAhrleisten. Diese Aufgabe kann mit Hilfe von Budgets, Verrechnungspreisen und Kennzahlen gelAst werden: Budgetierung strukturiert die Planung der in der kommenden Periode seitens der Benutzer benAtigten ADV-UnterstA1/4tzung und der dazu im ADV-Bereich vorzuhaltenden KapazitAten; Verrechnungspreise definieren die Schnittstelle zwischen der Benutzerplanung und der Planung des ADV-Bereiches. Kennzahlen schlieAlich kontrollieren und interpretieren die Wirtschaftlichkeit und steuern FlexibilitAt, Sicherheit und Benutzerzufriedenheit.

Die Entwicklung des EDV-gestutzten unternehmensubergreifenden Informationsaustausches gewinnt eine immer starkere Bedeutung. In fast allen Branchen sowie auf der Ebene von nationalen und internationalen Normungsgremien werden Losungen vorangetrieben. Die vorliegende Arbeit will eine geschlossene Darstellung der moglichen externen Informationsweitergabe mittels EDV geben. Damit sollen - am Beispiel von Handelsunternehmen - Funktionen aufgezeigt werden, die eine veranderte Ablaufgestaltung bei den beteiligten Unternehmen verlangen. Die Rationalisierungspotenti- ale fur die Unternehmen werden sowohl einzel- wie auch gesamt- wirtschaftlich aufgezeigt. Die Arbeit entstand wahrend meiner Tatigkeit am Institut fur Wirtschaftsinformatik an der Universitat des Saarlandes in Saarbrucken. Erfahrungen aus mehreren Projekten mit Handels- und Industrieunternehmen bildeten die Anregung und die Grundlage fur die Themenstellung. Mein besonderer Dank gilt meinem akademischen Lehrer, Herrn Prof. Dr. A.-W. Scheer, fur die wissenschaftliche Betreuung und die Unterstutzung. Herrn Prof. Dr. B. Tietz danke ich fur die Uber- nahme des Korreferates. Dank schulde ich vor allem meiner Part- nerin Hedwig Iro, deren Engagement und Verstandnis wesentlich zum Gelingen dieser Arbeit beigetragen hat.

Ebenso wie seine Vorganger liefert auch das 8. GI-Fachgesprach ein getreues Spiegelbild der Probleme, die sich in den jeweiligen Zeitraumen in den Rechenzentren ergeben haben. Zum Zeitpunkt des 8. Fachgesprachs bestimmen Themenkreise wie dezentrale Datenverarbeitung, ihre Beherrschbarkeit und ihre Grenzen, aber auch der Ausblick auf neue Techniken und Entwicklungstendenzen, Sicherheitsaspekte und Hochgeschwindigkeitsnetze die Diskussion. Die zunehmende Betrachtung der Rechenzentren unter Kosten-Nutzen-Gesichtspunkten fuhrte zum Themenkreis "Kapazitatsplanung und -management." Traditionsgemass wird auch dieses Fachgesprach von einer Hochschule, der Heinrich-Heine-Universitat Dusseldorf, ausgerichtet. Der Trend der Hochschulen - und damit auch ihrer Rechenzentren - geht hin zum Wissenstransfer und Technologieaustausch mit Unternehmen der Wirtschaft und Industrie. Berucksichtigt wird dies im Themenkreis "Kooperation Wirtschaft/Hochschule," in dem uber die Erfahrungen in der Zusammenarbeit zwischen Wirtschaft und Wissenschaft bei der Entwicklung komplexer Softwaresysteme berichtet wird."

Wahrend der Abwicklung komplexer DV-Projekte stellt sich den Verant- wortlichen haufig das Problem einer strukturierten Erfahrungsnutzung. Oft sind im Unternehmen bereits vergleichbare Aufgabenstellungen in fruheren Vorhaben gelost worden oder es waren ahnliche organisatorische Anforderungen zu bewaltigen. Gerade im Software-Bereich liegen auf- grund der naturgemaB starken Rechnereinbindung immer mehr Informa- tionen bereits digitalisiert vor. Der zunehmende Einsatz von Bl1rokommu- nikationssystemen leistet dazu einen weiteren Beitrag. Vor diesem Hinter- grund wird die automatisierte Auswertung und problemspezifische Aufbe- rei tung dieser Daten durch eine Erfahrungsdatenbank interessant. Das vorliegende Buch enthalt die Konzeption eines solchen Werkzeugs. Es wen- det sich vornehmlich an das Software-Management, Projektverantwortli- che und Stabsstellen, die die gewonnenen Erkenntnisse in einer organisati- onsspezifischen Realisierung umsetzen konnen. Die Erfahrungsnutzung in Software-Projekten ist sicher nicht durch eine ausschlieBlich theoretische Betrachtung zu behandeln. Daher bildet eine breite empirische Untersuchung des Informationsbedarfs von Software- Verantwortlichen und von ihnen verwendeter Methoden und Verfahren den Schwerpunkt dieser Arbeit. Dies war erreichbar, da der Zentralbereich Forschung und Technik der Siemens AG, Ml1nchen, das Vorhaben im Rah- men seiner Doktorandenforderung groBzl1gig unterstutzte und mir durch die fast dreijahrige Integration in geeignete Abteilungen und Projektum- gebungen interessante Einblicke und umfangreiche Recherchen vor Ort er- moglichte. Weiter wurden auch fur Detailuntersuchungen in Form von einigen Diplomarbeiten Mittel bereitgestellt. Die Leistungen der Verfasser sind im Text entsprechend hervorgehoben. Ich bin allen Damen und Herren der Siemens AG zu groBem Dank ver- pflichtet, die durch ihre konstruktive Mithilfe zum Gelingen der Arbeit beigetragen haben. Insbesondere sind dies Herr Jochen Platz, Herr Dr.
