RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

TelexPH has completed 48,000 image and text annotation tasks within 12 weeks, delivering six days ahead of the original schedule. The annotation throughput has increased from 2,800 tasks per week in the early stage to 5,200 tasks per week in the later stage — an increase of approximately 86%.Moreover, the annotation consistency rate (inter-annotator agreement) for the final delivery batch has reached 96.4%, exceeding the contractual threshold of 95%. The rework rate has dropped from 8.2% in the first week to 1.9% after the sixth week, showing a clear quality ramp-up.Additionally, the per-unit annotation cost is approximately 34% lower than our internal team benchmark. Through annotation guideline optimization suggestions proposed by TelexPH, review time for edge cases has been reduced by approximately 40%.

How did TelexPH perform from a project management standpoint?

TelexPH delivers on time and quickly answers our emails and messages.

What did you find most impressive about them?

What stands out most about working with TelexPH is their process discipline combined with genuine flexibility. From the start, TelexPH has operationalized the annotation guidelines we’ve handed them. They’ve built in daily quality spot-checks and weekly calibration meetings without being asked, and they’ve tracked inter-annotator agreement as a live metric rather than waiting for our QA team to flag problems. That proactive quality ownership is unusual in annotation vendors, where the default mode is often “deliver and let the client catch issues.”Moreover, TelexPH’s team actively challenges our annotation guidelines. They’ve flagged ambiguous edge cases early — before they become systematic errors — and have proposed concrete revisions to the labeling rules. Those suggestions have ended up cutting edge-case review time by roughly 40%. A vendor that treats the guidelines as a fixed contract tends to produce compliant but brittle output; TelexPH treats them as a working document and improves them.Additionally, they’ve assembled and trained a 15-person team within 10 working days. That responsiveness — combined with the fact that quality hasn’t dipped during the ramp — suggests they have a repeatable training playbook rather than improvising.

Are there any areas they could improve?

The only friction point is that their proactive style requires more of our time upfront — more calibration calls and more guideline iteration. It pays off in quality and rework reduction, but it’s worth knowing that this model works best when the client can invest early engagement time rather than treating annotation as a fully hands-off handoff.
