Prototyping – Mit geringen Mitteln zu viel Erfolg

„If a picture is worth 1000 words, a prototype is worth 1000 meetings.“ ( Die Entwicklung der User Experience einer App ohne Erstellung von Prototypen ist unvorstellbar. Zu wichtig und erfolgsentscheidend sind die Aufgaben, die Prototyping übernehmen kann: Kommunikation von Ideen zwischen den Stakeholdern (Business, Technologie, Design) Testen, Erproben und bewerten von Lösungsansätzen Lernen, lernen, lernen […]

IoT prototype – low-level thoughts about the 433mhz communication (part 4)
