5(16 reviews)Building apps is hard... when you're distracted.
Top awardedWhen hiring an app or web development team to build custom software, one variable matters most: are the developers fully dedicated to your success , or are you one client of many? Designli brings together designers, engineers, and business minds into on-demand, dedicated product teams that pour themselves, full-time, into the success of your app or web-app initiative. Existing as your dedicated software engineering department, we'll work together to solve your most pressing business problems with custom software. How it Works, and What We Can Build: Designli designs, develops, and launches beautiful apps and web-apps that you'll be proud to own, with a process that makes sense. Most importantly, we'll do this with a team that is assigned full-time to your project. With a step-by-step process, we'll begin by creating a clickable simulation of the User Interface of your app or website, and a development-ready backlog with each feature defined, estimated, and ready to code. Entrepreneurs use this output for fundraising. Business leaders use it for internal buy-in and market validation. When you choose to move into Development, our staff will be assigned full-time to you, and this team will be composed of the disciplines you need. Left alone, designers will create art projects. Engineers will create science fair gizmos. Business minds will create spreadsheets. Your development team will include all three, singularly focused on your success.

(0 review)Top awardedHallo, wir sind MING Labs. Wir arbeiten mit transformationalen Anführern weltweit und helfen ihnen dabei, sich in einer verändernden Geschäftswelt zurechtzufinden und relevante digitale Lösungen umzusetzen. Unsere Arbeit vereint Business Design, Experience Design und Technologie – alles Wichtige und Entscheidende, um Unternehmen beim Wachsen zu helfen und ihre Arbeitsweise zu verändern. WAS WIR MACHEN Wir arbeiten mit Unternehmen zusammen und helfen ihnen, ihre Prozesse und Arbeitsabläufe zu verändern, indem wir Best Practices aus dem Design in einen B2B-Kontext übertragen. Was ihr von MING bekommt, ist ein Team von, sagen wir, fünf Leuten, die tagein tagaus mit euch arbeiten und euch an einen neuen Ort bringen. Und das ist vielleicht genau da, wo ihr hinwolltet. EXPERIENCE DESIGN Ergebnisse: Customer Journeys, Service Blueprints, Experience-Prototypen, funktionale Prototypen, Visual Direction / Branding, Design-Systeme Jede Schnittstelle muss funktional und nützlich sein und den Menschen dabei helfen, das zu tun, was sie tun möchten. Gleichzeitig wollen wir, dass die Dinge etwas hervorstechen und implizit vermitteln, dass sie nicht nur funktional sind: Es geht auch um die emotionalen Aspekte, die für uns ziemlich wichtig sind. Übrigens designen wir nicht nur gut aussehende Mockups und machen dann Feierabend. Wir arbeiten auch an der technischen Umsetzung und begleiten sie bis ganz zum Schluss. BUSINESS DESIGN Ergebnisse: Opportunity Maps, Business Cases, Finanzmodelle, Value Propositions Beim Business Design geht es darum, euch zu helfen relevante Möglichkeiten zu finden, die zu wichtigen Veränderungen führen können (will heißen: viel Geld verdienen oder einsparen). Wir erwarten kein ausführliches Briefing und auch nicht, dass schon im Vorhinein alles für uns herausgefunden worden ist. Im Gegenteil. Wir freuen uns, wenn wir gemeinsam Dinge herausfinden können: Unsicherheit ist genau unser Ding und wir sind flexibel in unserer Herangehensweise. Wenn ihr schon eine Idee habt, in welche Richtung ihr gehen wollt, helfen wir sie mit potenziellen Kunden zu validieren und einen Business Case dafür zu entwickeln. ENTWICKLUNG Ergebnisse: Maintainable Quelltext, voll getestete Bereitstellung, Anweisungen & Dokumente, Test-Skripte / Test-Fälle Für uns ist das Design nur ein Teil der Arbeit: In der Entwicklungsphase fängt das Projekt wirklich erst an zusammenzukommen, und es gibt wenige Dinge, die wir spannender finden. Wir haben ein starkes In-House-Tech-Team (Architekten, DevOps, Backend- und Frontend-Entwickler, QA-Engineers, Projektmanager etc.), das die neuesten Tech-Trends kennt und einen stabilen und verlässlichen Prozess aufsetzen, durchführen und weiterentwickeln kann – mit aktuellen Tools und Methoden wie Scrum, Code-Review, fortlaufender Integration, fortlaufender Bereitstellung und automatisierten Tests.Looking for work in User TestingLocated in Munich, GermanyFrom €1,000 for User TestingWorks in multiple industriesSpeaks German, English51-200 members
