Research and Analysis: The first task for the Brrrief team should be to research the market and understand Astrum's target audience, business model, and competitors. This will give them insight into what kind of identity and logo would best represent the company and its values.

Conceptualization and Ideation: Based on their research, the team should start developing ideas for the corporate identity and logo. This may include sketches, mind maps, and mood boards that capture the essence of the brand. The team should aim to create a unique and memorable identity that differentiates Astrum from its competitors.

Design and Refinement: Once the team has narrowed down their concepts, they can start creating mock-ups of the logo and corporate identity. The team should iterate on their designs and make refinements until they have a final product that meets the client's needs and expectations. This may include multiple rounds of feedback and revisions to ensure that the final product accurately represents Astrum and its brand values.
