Sigma Engineered Solutions Wins Three Excellence Awards From Japan Institue of Plant Maintenance

Sigma Engineered Solutions® was presented with three Total Productive Maintenance (TPM) Excellence Awards from the Japan Institute of Plant Maintenance (JIPM) at an award ceremony held at the International Business Center in Kyoto, Japan. 

TPM is the maintenance technique that focuses on equipment and people to achieve Zero losses and improve productivity in all company functions.

The three Sigma Units which received these awards are:

  • Unit II Pune – A2/A3 Plant
  • Unit III Pune -A4 Plant
  • VKIA Jaipur – J0, J1, J2 and J3 plant

“Over the past five years, the teams at Pune and Jaipur have exhibited unwavering dedication and focus towards fostering a culture of excellence and achievement,” said Niteen Inamdar, Chief Operating Officer of Sigma Engineered Solutions.

It is no small feat to win one of these awards.  The criteria for these awards are not companywide, but JIPM judges each Unit, and Sigma was visited on two occasions for evaluations carried out by JIPM assessors from Japan to ensure we are focused on equipment and people to achieve Zero losses and improve productivity in all company functions.

"Our mission at Sigma is to create value for our customers as a trusted partner by delivering world class product solutions,” stated Brad Ward, President & CEO.  “This award is a testament to that mission and shows we continually strive for better not only for ourselves but our customers as well.”
