From a sentence spoken in a business to a working function

The main task in this role is translation. A business describes its problem in its own words. Out of that comes a technical concept, a project structure and finally a function that gets used day to day. Five examples from the BLUNATECH platform.

  1. What the business says

    In the morning we have no idea what is due this month on the marketing side.

    What was built from it

    Annual planning across twelve months

    Activities are picked from a library and placed on months. The year view shows all twelve months at once, instead of starting from scratch every month.

    Over 500 activities in 8 categories

  2. What the business says

    We never manage to write a newsletter on a regular basis.

    What was built from it

    Newsletter editor with a block system

    Content is built from prepared blocks instead of a blank page. Templates set the structure, the preview shows desktop and mobile.

    15 block types, 8 templates

  3. What the business says

    We honestly do not know where we stand on marketing at all.

    What was built from it

    Position assessment as a guided analysis

    The business answers structured questions and gets priorities for the coming months. No revenue forecast, just an order of play.

  4. What the business says

    After every trade fair we lose half of the contacts.

    What was built from it

    Contact Booster with a QR code

    A QR code leads to a form. The matching visual for posters and social channels is generated along with it, so the code actually gets seen.

    3 export formats: story, landscape, square

  5. What the business says

    We simply run out of ideas for what to write about.

    What was built from it

    Editorial desk with prompts and formats

    Topic prompts arrive sorted by category and are turned into the output format you need. The business picks from options instead of facing a blank sheet.

    8 categories, 5 output formats
