Previewlabs are skilled in delivering sophisticated prototypes. Needless to say, they have talented developers, who work in tandem with able project managers. They take the time to listen to the use cases, as well as think along with you. Subsequently, articulate the requirements to a Prototype Design Document (PDD) that forms the strong base.
Of special note, they are open to iterate the PDD through multiple reviews (scope, budget, deliverables). Subsequently, also gave us mid-term insights so that we all could re-align, in case of eventualities. Thus, setting right expectations.
Moreover, PreviewLabs do truly deliver what they highlight – a prototype, which is open for customers to improvise. Meaning, its not a black box. This is certainly beneficial in our case, as it enhances operational efficiency.
