flexneri by specific marker ions, demonstrating the potential of this method to differentiate between even closely related microorganisms. enterica were distinguishable from each other and from S. tropicalis could be identified by several unique markers compared with the other three organisms, and E. Characteristic marker ions were found for certain microbial cultures: C. Headspace VOCs in sampling bottles containing actively growing cultures and uninoculated culture medium controls were sequentially analyzed by PTR-MS. The novel PTR-MS method was evaluated for four reference organisms: Escherichia coli, Shigella flexneri, Salmonella enterica, and Candida tropicalis. A newly developed sampling system was coupled to a PTR-MS instrument to allow on-line monitoring of VOCs in the dynamic headspaces of microbial cultures. Early collaboration with engineers was vital, so I knew solutions were feasible for the app infrastructure.ĭesign team used Trello for project tracking, Miro or FigJam for workshops and brainstorming sessions, Maze or Typeform for user testing, and Slack for communication.A method for analysis of volatile organic compounds (VOCs) from microbial cultures was established using proton transfer reaction-mass spectrometry (PTR-MS).

I always started with a problem, dug into data, talked to users, did competitor research, analysed it all, and had brainstorming sessions to develop solutions. One designer owned the project from start to finish. It's not fixed and is constantly adapted to specific project specifics. Over time, as the product matured and the team grew, we incorporated a more comprehensive design process (our documented process is in the image below). Experiments with trial and error were vital.


It gave us fast feedback and leeway to adapt to changes incrementally.

At the start, we relied on Lean UX, meaning business-hypothesis driven, experiment-based and iterative.Īs a general rule, we worked in Shape Up's six-week cycles, aiming to complete the whole project from start to finish. We always had to tailor it to specific objectives and act fast with the time and resources we've got. The design process in startups isn't the most conventional of all.
