- Himadri Sarkar explains his lean six sigma black belt project at Hutchison 3 Global services.
- In a large telecom company, it was found that the order error rate for order provisioning campaigns is as high as 14 %. Various reasons were identified including – incorrect code assignment, duplicate orders, incompatible orders accepted, order entry errors, code errors etc. A Six Sigma DMAIC project was taken up that successfully brought down the order error rate to 1%. The success of this project led to more than 4 million saving in addition to reduction in customer complaints and dissatisfaction.
- Value added Services (VAS) reversal in prepaid connections has been the biggest issue for Customer Service of a large mobile services provider. On detailed analysis, it was found that customer service agents were erroneously de-activating value adding services while providing customer service. FMEA was used to find out the possible causes of such failure modes in the entire range of customer service activities. A control plan was created to ensure that inadvertent errors came down. Additional controls were implemented for correction as such manual errors could not be totally eliminated - the change in VAS service was made impossible without customer’s recorded concurrence. As 100% recording was initiated, each case became verifiable and led to increased consciousness among agents. Reduction in VAS reversal complaints led to higher customer satisfaction as well as increased revenues.
