How AI HR Senior cut HR answer prep from 30m to 5m
Food manufacturing and distribution
A 1,000-person food manufacturer cut repeated HR answer prep from 30 minutes to 5 by pairing AI HR Senior with a source-linked internal knowledge library.
The documents existed. The answers still lived in people's heads.
Office staff, factory workers, and foreign workers followed different rules, and questions arrived through four separate channels
The client is a mid-sized food manufacturing and distribution company with about 1,000 employees. Its workforce is split across office staff, factory workers, and foreign workers. Leave, allowances, expense handling, and onboarding rules vary by group. Some answers were available in ERP or groupware. Others lived in shared files, NAS folders, personal notes, or spreadsheets used only for foreign-worker guidance. Questions came through HR, general affairs, accounting, and site managers. To answer one question, an operator had to check recent support cases, the document used last time, the original policy, and often the memory of a long-tenured colleague. The same question could sound different depending on who picked it up. Even deciding whether a case needed outside labor counsel took time.
Specific pain points
•Office, field, and foreign-worker rules changed the answer to otherwise similar questions.
•Onboarding material was scattered across folders, NAS shares, and personal notes, so quality depended on the operator.
•ERP, groupware, spreadsheets, and affiliate documents made it hard to know which source was current. Repeated answers took about 30 minutes to prepare.
•Questions arrived through HR, general affairs, accounting, and site managers, so the same issue could get different wording or even a different conclusion.
•Performance tools already existed, but connecting ratings, shift rules, allowances, and payroll logic into one explanation was hard.
•Repeated questions were not archived with their source documents, so the same research kept happening.
•Operators also had to decide whether a question could be answered internally or needed outside labor counsel.
“The documents were there. The hard part was finding which one mattered. The answer changed depending on whether the person was office staff, field staff, an affiliate employee, or a foreign worker. Most days, the fastest route was still asking the person who had been around the longest.”

We built the knowledge library first, then put AI HR Senior on top
No chatbot shortcut. The team needed a reliable base of HR knowledge before the agent could help.
The visible deliverable was AI HR Senior, an HR-focused AI Agent. The real starting point was the internal HR knowledge library behind it. We gathered work rules, benefits guidance, groupware notices, expense policies, and foreign-worker spreadsheets into a single source of truth. During a three-month pilot, questions that had been scattered across four channels moved into one AI HR Senior channel. Office, field, and foreign-worker rules stayed separated inside the library, so the agent could retrieve the right context before drafting. We started with HR support, then expanded into onboarding and training, and finally into payroll and performance review. We did not try to automate the whole HR function at once. We moved the daily repeat work first.
We did not begin by uploading every HR file we could find. We first sat with recent support cases and watched how operators actually answered them. A question might start in the work rules, move to a benefits guide, then jump to a groupware notice, an expense policy, or a spreadsheet for foreign-worker guidance. That path mattered. The knowledge library had to follow how the team really worked, not how the folders were named.
HR policies, guides, FAQs, and onboarding material are cleaned into question-sized chunks and made searchable.
AI HR Senior retrieves the source, drafts the answer, attaches links, and keeps a review log.
The cleanup work was less glamorous than the agent, but it decided whether the agent would be useful. PDFs, Word files, Notion pages, web documents, and spreadsheets could not go in as-is. We removed repeated headers, split long documents into question-sized chunks, and tagged them with the words employees actually used: travel expenses, shift work, foreign-worker onboarding, performance bonus, groupware expense handling. That made retrieval work even when the question did not use the exact wording in the policy.

Knowledge-library pipeline. Documents and support history are cleaned, tagged by role and topic, retrieved for drafts, and then improved through answer logs.
Once the library was usable, we connected AI HR Senior. The rollout still needed people work. HR operators, site managers, and affiliate contacts had different habits, so we agreed on operating rules together. Which questions can the agent draft directly? Which ones need admin review? Which ones reveal that the source document itself is unclear? OTOworks stayed close to real support cases while those rules settled. That is why AI HR Senior feels less like a bot and more like a senior teammate who pulls the right evidence before you answer.
The first live scope was HR support. Take a question like, 'How does annual leave carryover work for field employees?' AI HR Senior checks whether the office and field rules differ, whether statutory rules or internal policy apply, and whether an affiliate exception matters. Then it pulls the relevant policy chunks and FAQs into a draft with source links. The operator is no longer staring at a blank page. They are reviewing evidence and deciding exceptions.
Next came onboarding and training. The existing material was mostly files, and every operator explained it a little differently. We did not try to solve the whole area at once. We first mapped the basics: employee type, site, procedure, required documents, training items, and owner. That lightweight ontology gave the library enough structure to serve different guidance for new hires, factory workers, foreign workers, and affiliates. Pre-start instructions, factory safety training, residence-document guidance, and groupware onboarding could finally be found by context instead of folder location.
Office, field, and foreign-worker guidance stay separated, so onboarding answers come from the right context.
The third scope was payroll and performance review. The client already had performance criteria and tools. The hard part came when ratings affected pay or bonuses. Office roles leaned on ratings and goal achievement. Factory roles added shifts, overtime, night work, and production-line rules. Foreign-worker cases added visa, contract, and allowance context. A black-box calculator would have been the wrong answer. We organized the rules, evidence, and review questions so AI HR Senior could assemble what an operator needed to check.
The admin view brings together performance results, allowances, exceptions, and payroll evidence for review.
We kept this part deliberately conservative. Compensation questions should not be finalized by an AI system alone. AI HR Senior summarizes the performance rating, worker type, work pattern, allowance rule, and source policy. Sensitive or unusual cases stay in the admin-review queue. The team gets a faster review packet, but the final call remains with a person. That made adoption easier, especially for payroll and performance work.
The last piece was logging. Every question, source document, answer draft, and admin edit is kept. Those logs are not just audit history. They show what to fix next. Repeated questions become FAQ candidates. Questions with weak evidence become document-backlog items. Affiliate-specific exceptions get their own tags. The more the system is used, the cleaner the library gets, and the more stable the answers become.
What the system includes
AI HR Senior for HR support
Understands employee questions, retrieves source documents from the knowledge library, drafts an answer, attaches links, and flags whether admin review is needed.
Internal HR knowledge library
A single source for office, field, and foreign-worker rules, separated by question context. AI HR Senior checks this library before drafting. The same pattern is available in the public hr.otoworks.ai demo.
AX training and field rollout
Support-channel habits were mapped before automation. OTOworks worked with real cases to decide what the agent drafts, what admins review, and what documents need cleanup.
Personalized onboarding and training
Employee type, site, procedure, required documents, training items, and owners are lightly structured so each group gets the right guidance.
Payroll and performance review support
Ratings, allowances, payroll rules, and source policies are pulled into one review packet. Sensitive exceptions stay under admin review.
Document improvement from question logs
Repeated questions, missing sources, and admin edits become the backlog for improving the knowledge library.
HR answers now start from evidence, not memory
Repeated questions are faster. Sensitive ones are easier to review without losing control.
After the three-month pilot, the biggest shift was where each answer began. Before, even repeated questions often took close to 30 minutes because operators had to reopen documents or find the colleague who remembered the exception. Now AI HR Senior clarifies the question and worker type first, then retrieves the relevant policy and draft from the knowledge library. Operators review an evidence-backed answer instead of writing from scratch. Payroll and performance questions are handled more carefully. The agent does not make the final call. It organizes the rules and evidence, then routes the case to admin review. Speed improved, but control stayed with the HR team.

Governance
Every answer keeps source links and admin-edit history.
What changed in practice
Repeated questions take less operator time
Annual leave carryover, benefits, travel and meal expenses, groupware expense handling, and onboarding questions now start as evidence-backed drafts. Operators check exceptions and wording instead of starting from zero.
Answers sound more consistent across channels
Common rules live in the knowledge library, while affiliate and role exceptions are tagged separately. The same question is less likely to drift into different answers depending on the channel.
Onboarding no longer depends on one person's memory
Worker type, site, required documents, training items, and owners are structured enough for AI HR Senior to pull the right guidance when hiring spikes or operators change.
Payroll and performance questions are safer to review
AI HR Senior does not finalize sensitive compensation answers. It bundles rating, role, work pattern, allowance rule, and source policy, then routes high-exception cases to admin review.
Document gaps became visible
When the library cannot support a good answer, the log captures it. Those gaps become the next quarter's document-cleanup backlog.
“Before, every question started with, 'Who knows this best?' Foreign-worker documents, field-worker shift allowances, affiliate travel expenses, all the questions with branching rules were fastest when we could ask the long-tenured person. If that person was out, the answer stalled. Now AI HR Senior identifies the worker type and context first, then shows the related documents, previous answers, and whether admin review is needed. It makes the part that needs human judgment much clearer. For payroll and performance, I actually like that the AI does not make the final decision. It gathers the evidence. The speed helps, but the bigger change is that answers across channels finally sound consistent.”
