Product development

We conducted a series of interviews with different representatives of the target audience and an on-site workshop with the DTEK team to understand their customers' business objectives.

We summarised the results as requirements for the future platform development:

  • Payments history, review the previous meter readings to see the dynamic of the energy consumption throughout a year
  • Receive uncluttered, easy-to-navigate bills with all the relevant information on them and the ability to pay them remotely
  • Easily keeping up with current debt, relevant fees, charges, and planned power outages
  • As a result - to create positive customer interactions and simplify communication and information sharing. Avoiding talking on the phone in case of a power outage or any other issue
