Tenders","group":"Production","sector":"31-33","jobZone":2,"jobZoneInferred":false},"framework":{"version":"v.26.05","description":"","contextCovered":"This framework covers industrial production environments where operators set up, run, maintain, and monitor crushing, grinding, and polishing machinery to process raw and semi-finished materials, spanning entry-level floor work through lead-level process ownership.","levels":{"emerging":{"label":"Emerging","statements":["Crushing and grinding machine controls — identify and operate under direct supervisor guidance on a production floor.","Equipment malfunctions and flow irregularities — recognize and report to a supervisor during monitored machine runs.","Hand tools and basic cleaning supplies — use to clean and wipe down equipment surfaces following a posted maintenance checklist.","Accessory equipment such as pumps and conveyors — tend under direct instruction to move materials through a basic production process.","Raw materials and finished products — weigh and measure at specified intervals using calibrated scales under close supervision.","Defective output samples — identify and set aside for supervisor review according to facility quality standards.","Production log forms — record basic operational data and shift counts with guidance from a lead operator.","Personal protective equipment and site safety rules — follow consistently at all times on the plant floor.","Supervisor repair notifications — communicate verbally and in writing when equipment issues are observed during a shift.","Standard operating procedure documents — read and follow step-by-step to start and stop assigned crushing or grinding machines."]},"developing":{"label":"Developing","statements":["Crushing, grinding, and polishing machine settings — adjust and control independently to maintain consistent material output within specification.","Equipment flow and operational continuity — monitor across a full shift and make routine corrections without supervisor prompting.","Hand tools and lubrication supplies — use routinely to clean, adjust, and maintain equipment according to a preventive maintenance schedule.","Pump and conveyor accessory systems — tend and troubleshoot to keep material moving efficiently through multi-step production processes.","Material weights and measurements — record and compare against production specifications at defined intervals to ensure conformance.","Defective products — reject and readjust machine parameters to correct recurring quality problems within familiar process conditions.","Spreadsheet and word processing software — enter and organize daily production and testing data on electronic forms.","Operational changes and repair needs — communicate clearly to supervisors and peers using accurate production terminology.","Time and task priorities — manage across concurrent machine assignments to minimize downtime during a standard production shift.","Quality control inspection steps — apply consistently to sampled materials, documenting results on required forms with minimal errors."]},"proficient":{"label":"Proficient","statements":["Full range of crushing, grinding, and polishing equipment — operate and control autonomously across diverse material types and production conditions.","Non-routine equipment malfunctions — diagnose root causes and implement corrective adjustments without waiting for supervisor direction.","Preventive and corrective maintenance tasks — perform independently using a full set of hand tools to minimize unplanned production stoppages.","Accessory pump, conveyor, and blending systems — oversee and fine-tune to optimize material flow across a complete production line.","Measurement data and quality control records — analyze trends over time to identify process drift and recommend specification adjustments.","Defective product patterns — evaluate systematically, adjust multiple machine parameters, and verify resolution through follow-up sampling.","Enterprise resource planning (ERP) software — input production data, track material consumption, and generate shift summary reports accurately.","Equipment repair needs — assess severity, prioritize, and communicate detailed findings to maintenance and supervisory staff to expedite resolution.","Safety and operational risks — evaluate in real time and apply sound judgment to stop or adjust processes before incidents occur.","Production schedules and quality targets — coordinate personal workflow to consistently meet or exceed output and conformance requirements."]},"advanced":{"label":"Advanced","statements":["Machine setup standards and operating procedures — develop and document for the full crushing, grinding, and polishing equipment suite used at the facility.","New operator onboarding and skills training — lead structured on-the-job instruction sessions that build proficiency from day one through independent operation.","Facility-wide production flow and equipment reliability — oversee and continuously improve to maximize throughput and minimize material waste.","Quality control systems and inspection criteria — establish, audit, and refine across the production line to ensure sustained conformance to specifications.","Preventive maintenance programs — design and implement schedules for all accessory and primary equipment to extend service life and reduce downtime.","ERP and production reporting systems — champion adoption and accurate use across the operator team to support data-driven management decisions.","Cross-functional communication between production, maintenance, and management — facilitate to resolve complex equipment and process challenges at organizational scale.","Safety culture and regulatory compliance — model and reinforce through daily practice, toolbox talks, and participation in site-level safety reviews.","Performance metrics and production KPIs — analyze shift, weekly, and monthly data to identify gaps and lead corrective action planning with supervisors.","Process improvement initiatives — lead evaluations of equipment configurations, material handling methods, and operator practices to raise departmental efficiency."]}}},"sources":{"onet":"v30.2 (CC BY
