Case Study

A global provider of communication networks required improvement in the product performance of a telecom application using Six Sigma methodologies

The customer

A US based leading provider of communication networks required improvement in the product performance of a telecom application using Six Sigma methodologies.

The challenges

	Reduce the data transfer time
	Reduce the risk
	Avoid interruption due to LAN/WAN Downtime
	Parallel availability of the switch for other administrative tasks during the same period

Solution

	Wipro deployed a team of Black and Green belts to adopt DMAIC (Define, Measure, Analyze, Improve and Control) Six Sigma Methodology.
	By adopting a systematic approach to analyse the data and by the usage of Statistical Analysis Software, Wipro zeroed in on the problem.
	Design changes were carried out while studying side –effects and the implementation was validated by testing on a lab setup and by confirming the usage scenarios by the end user.
	A new algorithm was designed and implemented.

Measurable, tangible results delivered

The Six Sigma Process resulted in an achievement of close to 250%, 6 minutes for 1 MB transfer and 18 minutes for average data transfer. The set target was 200%

Based on these results, the changes were included in the subsequent releases of Product X. Operation Downtime was reduced by reducing data transfer duration, risk of the operation being interrupted by LAN/WAN downtime is automatically reduced. The switch availability was also increased as the data transfer time was reduced.

Overriding benefit

The performance enhancement enabled the client to have an improved product with the overriding benefit that the End Customer perception of the quality of the Client’s product is improved.
