The company is following Quality Assurance system as per ISO 9001-2000 standard. The Quality Policy of the company is
"To provide products meeting
customer satisfaction with
excellence in performance and
cost effectiveness through a Continually Improving Quality Management System".
Some of the important features of the quality system are described below.
1. DESIGN REVIEWS
Design reviews are conducted at various stages of design and development activities. Design validation reports, development-testing reports, qualification testing reports, field trials performance reports, and drawings and documentation prepared for production, form the inputs for design reviews.
2. NON-CONFORMANCE REVIEWS
The inward inspection reports, in-process inspection reports, final inspection reports, customer complaints and reports from Service Engineers are reviewed periodically during non-conformance reviews. Major or repetitive non-conformances are identified for detailed investigation. Corrective actions are decided based on the results of these investigations and analysis. Necessary process improvements and design improvements are carried out based on these reports.
3. CALIBRATION OF TEST EQUIPMENT
All the test & measuring equipment, gauges, jigs & fixtures used at various stage inspections & final testing, are periodically calibrated. Wherever internal facilities do not meet the requirement, calibration is done externally at approved laboratories, where calibration facilities traceable to National Standards, are available.
4. VENDOR RATING
The performance of suppliers for various raw materials, and components is assessed periodically and vendor rating is carried out. Vendor rating forms an important input, while deciding the placement of orders on suppliers.
5. TRAINING
All the employees are periodically trained to improve upon their skills and knowledge. Customer representatives, who are involved in the maintenance of the equipment, are also trained in the aspects of maintenance and testing.
6. QUALITY AUDITS
Quality audits form an important part of quality assurance program. Performance of quality functions at various departments, their documents and quality records are audited periodically as per a detailed timetable. All non-conformances are recorded and corrective action plans are drawn. Implementation of corrective actions also forms one of the inputs for future audits. The top management periodically reviews the reports during management reviews. Apart from monitoring the performance, this would help in improving the quality system as a whole.
7. BURN-IN PROCEDURES
The raw materials and inputs are tested for specified performance. On all electronic components, passive Burn-In tests are conducted to eliminate infant failures. On all power handling components, active Burn-In tests at enhanced power levels are conducted in custom made test jigs, and variations in certain parameters are recorded to judge the life expectancy of the components.
8. INSPECTION & TESTING
The equipment in production undergoes various stages of inspection for Quality Assurance. Stage inspections and sub-assembly level tests are conducted to monitor various parameters. Random sampling and SQC techniques are used to ensure consistency of the production process. Detailed inspection and performance tests are conducted on the final products before dispatch, to ensure consistent quality levels.
At periodic intervals randomly picked up sample units are sent to Electronics Test and Development Center, an accredited laboratory, for conducting environmental and enhanced Life tests. This is a Government of India Organization under the ministry of information & Technology.
9. CONTINUAL IMPROVEMENT
All the data collected through Internal Audits, Corrective Actions, Preventive Actions, Management Reviews, Customer Complaints, and Field Failures etc., is monitored and analyzed and Targets set for bringing Continual improvement in the Quality Management System and Products & Customer Services.
