Strategic Design Base

We manage all of our projects strategically, with the aim of integrating all stakeholders and strengthening the product brand and corporate identity in a sustainable manner and based on a coherent design language. To achieve this, we set goals, define the process and methods, develop design systems and support the realisation of the design strategy across all business units.

We review the task at hand in the context of the product’s ecosystem. We analyse the corporate and brand context, determine the design requirements, while incorporating technical framework conditions as well as feedback from the market. Your added value: a solid basis for a brand-consistent user experience that also considers any future design developments.

We plan the entire design process and advise you regarding the individual steps and an effective use of methods to ensure that your project progresses smoothly and you accomplish the defined goals within the agreed timeframe.

We develop visual brand languages and design system documentations to strengthen brands internally and externally, to assure quality, and to enhance the efficiency of future design developments.

We support our clients in anchoring their new design strategy in the entire company. Because a product’s design quality can only be increased sustainably if the new design is understood, internalised and embraced by all stakeholders.

Creative Design Core

To swiftly arrive at innovative and resilient solutions that meet the needs of prospective users, we harness the creative potential of everyone involved. As part of interdisciplinary stakeholder teams, we jointly develop new, creative ideas that are subsequently specified and visualised and thus become tangible and understandable. To communicate our solutions to engineers and programmers, we create design specifications for a successful implementation.

We analyse the task at hand in the context of the product life cycle, with a focus on the user. We talk to future product users and review each and every step. We look into the product’s environment, technology and features, the market and the brand. Based on this, we develop holistic requirements for the design process.

Following the analysis, we host ideation workshops and design sprints with different stakeholders. We make use of a range of creativity techniques to get off the beaten track and to generate as many original ideas and visions as possible.

We translate ideas into coherent overall concepts, visualise them and make them tangible and understandable. The aim is to obtain initial feedback from users and stakeholders and to prepare for the next decision-making steps. Based on the selected concept, we develop alternative design directions and optimise the chosen design as part of an iterative, multi-stage process.

For the implementation phase, we document all relevant details and provide you with the graphic components. As engineers, we communicate with our partners and speak the language of their customers. And our experienced engineering partners are always happy to assist you as needed.

Agile Design Proof

In the course of the design process, we develop prototypes and conduct usability tests to repeatedly assess a product’s usage scenarios, ergonomics and visual design and to make ideas tangible at the earliest stage possible. In close collaboration with engineers and programmers, we supervise the implementation in series production and, where necessary, make final adjustments to ensure the standards for optimal design quality are fully met.

Throughout the design process, we use physical and virtual models in order to test and to iteratively refine their form, function and usability. To this end, we create models in our workshop, print prototypes on our 3D printer, create VR models from our 3D CAD design data, and develop wireframes and interactive click dummies. Only verified designs will be handed over for implementation.

In one-on-one interviews or group discussions, we evaluate the suggested solutions in terms of their usage scenarios, ergonomics and visual design. User acceptance and feedback are thus incorporated into the design iterations early in the process.

Our engineers, ID, UI and UX designers speak directly with your development engineers and manufacturers, developers and programmers to ensure optimal design quality. The implementation support provided by our design experts represents the final stage of zweigrad’s end-to-end quality management process.
