Inside Our ISO 21998 Journey – Mariko Hummel-Jibiki
As part of our journey towards achieving ISO 21998 Healthcare Interpreting, we asked Mariko, INZ Operations Lead, to reflect on her experience during the certification process and the audit. Here is what she shared.
How did going through this certification process make you consider the needs of interpreters?
“As an interpreter myself, I naturally consider the interpreter’s perspective in all aspects of our work. However, going through this certification process reinforced just how important it is for interpreters to receive clear and sufficient information about their assignments so they can prepare adequately, ensuring both their safety and the quality of the service.
It also reminded us that providing this level of information is not always straightforward, given operational pressures and privacy considerations, but it is something we must continue to work towards.
Feedback from interpreters has been an important part of this process, and we have been taking practical steps to improve how information is shared so that interpreters feel supported and well prepared for their work.”
What challenges did you face taking the auditor through the lifecycle of an interpreter, from employing them to ensuring their work is achieved?
“I had never experienced a multi-day auditing process before, and it took some time to fully understand what the auditor was looking for. At moments, I wished I had an interpreter for myself!
What I did have, however, was an incredible team I could rely on. Colleagues contributed insights I might have missed, clarified points when I was unsure, and were able to answer questions when I needed to redirect. Other colleagues were also on standby if needed.
Knowing we had such a strong, dependable team inside and outside the meeting room allowed me to confidently address questions and ensure that every aspect of the interpreter lifecycle was covered. Teamwork and mutual support were key to successfully navigating the audit.”
What would you recommend to other organisations aiming to achieve this ISO standard?
“If we have confidence in, and take pride in what we are doing, it needs to be reflected in clear processes, consistent practices, and systems that everyone can rely on.
Supporting staff through guidance, training, and open communication makes a big difference.
Achieving the standard isn’t the end point — what matters most is continuing to improve, adapt, and work together across the organisation.”
Thank you, Mariko, for sharing your reflections and for your leadership throughout this process.
