【Company B】Maximizing the use of telework office resources for annotation tasks.


Company B, a prominent consulting firm, has approached us with a subcontracted annotation task from an AI development company. They are seeking our expertise to efficiently handling these sizable tasks without compromising on quality.


While automation has advanced in the creation of training data (annotation) for AI development, many aspects still require manual intervention.

Although outsourcing to overseas locations is often employed to reduce costs, maintaining the same level of quality as domestic operations remains a challenge.

B Company has been receiving an influx of requests for the development of higher-quality training data from major AI development companies, similar to those received by other industry leaders. To meet these demands, B Company has been utilizing their network of online teleworkers situated across different regions nationwide up until now.

Team Member Testimonials

Idea Plus Director Nakadaira

When dealing with projects that have extensive guidelines, it can be challenging to effectively communicate and improve quality within a short period or one-time basis. However, with this project that were of a medium to long-term scope, working with partners in a telework office allowed their skills to improve over time. This then enabled us to deliver high quality results at a competitive price point.
Our objective is to continuously enhance our clients’ business efficiency by leveraging telework offices to extract and manage time-consuming tasks that arise on a day-to-day basis.

Idea Plus Partner

I was able to benefit from the insights and tips I gained from doing this task in a different telework office before, which enabled me to put that previous knowledge to good use.

*At Idea Plus, we collaborate with creators such as designers, photographers, account planners and so on and so forth.


I can’t stress enough how much I appreciated the convenience of having a designated platform for making requests, rather than approaching individuals one by one. This was especially beneficial for projects that involve selecting individuals, such as medical annotation, where managing the difficulty level for each person can be tricky.

Being able to tackle all those challenges smoothly was incredibly helpful. We look forward to working with you again when similar projects come up.

Here are some other case studies, written in Japanese however. Please feel free to have a look.
