Projekt Vollautomatisierte Rückmeldeprozesse für Erhebungsdaten, 11/03 - 11/03
Referenz durch Leiterin Kommunikation, Forschungsinstitut (ca. 180 MA), vom 24.09.08
"[...] Die beiden Consultants ermöglichten dank ihres Engagements und Know-hows die erfolgreiche, alle Ansprüche in höchstem Maße befriedigende technische Umsetzung des Projektes. Durch ihre schnelle Erfassung und Analyse der vorliegenden Problemstellung konnten sie umgehend einen Lösungsansatz entwickeln, der eine vollständige Erfüllung der Anforderungen trotz eines äußerst knappen Zeitrahmens ermöglichte. In der praktischen Umsetzung konnten uns Erfahrung, Zuverlässigkeit und Sorgfalt der Consultants überzeugen, die für den fehlerfreien und termingerechten Abschluss des Projekts entscheidend waren. Ihre Professionalität und Bereitschaft, sich auch auf schwierige Rahmenbedingungen einzulassen, haben maßgeblich zum Erfolg unseres Projekts beigetragen. Wir sind ihnen für ihren sehr engagierten Einsatz dankbar und können sie sowohl ob ihrer fachlichen als auch persönlichen Qualitäten ausdrücklich empfehlen. Wir werden sie bei Bedarf jederzeit gerne wieder einsetzen."
Projekt Datenbank und Web-Frontend für Unterrichtsmaterialien, 04/03 - 12/03
Referenz durch Direktor, Staatl. Sem. für Didaktik und Lehrerbildung, vom 02.09.08
"[...] Er hat diese Arbeiten in Zusammenarbeit mit einem weiteren Consultant nach der Entwicklungsmethode des Pair Programming durchgeführt. Die beiden Consultants waren für die technische Umsetzung unserer Anforderungen in allen Phasen des Projektes voll verantwortlich. Sowohl in der Planungsphase als auch während der praktischen Umsetzung und im Verlauf des anschließenden Testbetriebs erwiesen sie sich als ausgesprochen kompetente Ansprechpartner, die über die rein technischen Aspekte hinaus einen guten Blick für die Interessen und Ziele des Kunden haben. So konnten sie im Zuge der Entwicklung zahlreiche Vorschläge einbringen, die es uns ermöglicht haben, das Endprodukt über unsere Spezifikationen hinaus weiter zu verbessern. Überzeugt haben uns auch die sehr kurzen Reaktionszeiten im Rahmen der Anwendungsbetreuung. Der laufende Betrieb und die Verfügbarkeit der Anwendung waren dadurch jederzeit sichergestellt, sie ist seit ihrer Fertigstellung in konstantem Einsatz und erweist sich als robust und alltagstauglich. Für den mittelfristig geplanten Ausbau der Anwendung werden wir gerne auf die Consultants zurückgreifen."
This implies building an initial version of the software (reduced to a few core functionalities but already usable) at the earliest point in time possible. Through frequent releases of the most current development status in close and constant cooperation with the customer, the software will then step-by-step be expanded to its complete functionality. This approach allows to identify the possible need for changes and/or extensions early on in the development process and to prioritize them accordingly.
Internally, this is put into practice particularly by the use of Test-Driven Development (each new functionality requires a proper test first) and Continuous Integration (each new development step will be promptly integrated into a working version of the software which can be released immediately).
In addition, the use of Pair Programming (two developers are working on one functionality together at the same time) has proven to be very efficient. The increase in speed and quality achieved by this 'dual control principle' surpasses the additional assignment of manpower significantly and - contrary to common expectations - results in reduced development costs!
I have already completed several projects using this technique in close cooperation with other freelancers. A certain freelancer belongs to my established and well proven pair programming partner. We have been working together as an excellent team for several years already (which is reflected in some of our listed projects) and are especially interested in related requests.
