Background
In 2003, the senior management of OurBank decided to adopt and implement Six Sigma as their business management tool across all business units in the Europe region.
According to the OurBank business strategy, the car loan business was identified as one of the business priorities in the next 12 months. The strategy was to significantly grow the car loan business market share within the region in two years time, by 100% in the first year, and by another 70% in the second year.
Pre-Analysis Phase
The team created a high-level process map and identified the sub-processes and the relevant influence factors. The identification of the indicators was achieved through a series of interviews with a lot of process stakeholders. They did not know about process indicators but they were able to express what kind of “critical numbers” they looked at monthly. Some of those numbers could easily be translated into indicators; others needed more effort to become obvious.
Examples for process indicators: # contacts/month, # complaints from car dealers, car dealer turnover/month, % abandoned calls, speed of answer in sec.
A key success factor of this exercise was to have the respective sub process owners contributing to pinpoint the specific problem areas.
From this pre-analysis, the team identified two Black Belt and two Green Belt projects. The distinction between Black Belt and Green Belt was made depending on the urgency of the task. They reasoned that full-time Black Belts can deal with the problem faster and more effectively than part-time Green Belts.
Project Definition
The final project definition for one of the Black Belt projects had a narrow scope including only one sub-process: Communication with car dealers. After the interviews and after pulling some data from the Management Information System one of the reasons for starting this project was the recognition that more than half of the car dealers has not done any business over the last couple of months. In addition, some marketing data told the team that it was much more expensive (about 500%) to acquire new car dealers than to work with existing ones.
One of the biggest obstacles at this point was engaging the process owner in the project. The car loan business process owner – the sales director – was one of the few that were quite sceptical towards Six Sigma. Additionally, the team was not used to working as a team: Different office locations for marketing/sales and Operations led to a break-down of communication between these functions. The first team meeting was a very quiet exercise with obvious as well as hidden finger-pointing.
However, the Belt Black Belt did an excellent job in influencing the process owner, by helping him to understand and see the benefit of Six Sigma.
Lessons Learned:
- Demonstrate right from the start that Six Sigma is an imperative that contributes to the strategy of the company.
- Demonstrate the need for the Six Sigma projects rather than starting some “learning and training projects” only.
- Make sure you organise the buy-in of the senior management first.
- The Voice Of The Customer is key
During the interviews performed to identify business indicators and to determine their base-line, the team experienced a very common opinion expressed by sales staff: “We could generate more turnover if we had better conditions.” This is never a surprise in any business in the world. However, the team decided – as part of Measure Phase – to explore the Voice of the Customer even more. Supported by an external market research company they developed a client survey that was conducted with about 130 car dealers. The result was a big surprise:
- 60% of the interviewees mentioned the non-existing or poor communication with the bank as the biggest driver for dissatisfaction.
- For about 20% the interest rate for the car loans seemed to be too high.
During the Analysis Phase the team focused on those two issues. They went through the process of communication between the sales team and the clients. Surprisingly, they recognised that there was no process. The sales representatives complained about the workload they had to do every day. They were kept busy by preparing reports, sales presentations and a lot of internal meetings. They did not really focus on talking to their clients. “If I have some time left I give my clients a call.” was one of the typical comments.
The analysis of the interest rate revealed an additional, and even worse issue: Some of the clients did not know the newly-reduced interest rate of OurBank .
After further analysis the root-cause for this serious fault was explored as the communication channel between marketing and operations not working very well. Immediate action was taken to inform all clients about the better rate.
Lessons Learned:
- Don’t assume you know what the customers want. Ask them.
- Six Sigma is not about blaming people even if you see “unbelievable” weaknesses. People are not the problem. Fix the process and allow the people to do their jobs.
Implementing Solutions And Sustaining The Gain
- Development of a communication process between sales representatives and clients
- Development of a monitoring tool to alarm sales in case of inactivity of clients
- Refinement of the roles of Marketing, Sales and Operations resulting in taking some administration work off the sales force in order to give them the chance for their first priority: talking to the clients
- Redefinition of internal interfaces to improve communication between departments
- Layout of a Marketing Handbook to support clients selling OurBank’s services
- Communication with the whole organisation.
- Describing the new process in the Operational Manual.
- Training of all people involved in the process on the changes.
- Measuring the process means changing the behaviour of the people. Measuring the right indicators means changing the behaviour in the right direction. You will see some improvements shortly after having started the data collection. But don’t assume these improvements will stay for longer than you measure unless you implement some tools that help to sustain the gain.
- Involving clients in project work is a challenge at the beginning because you “open the book” to them. After this sometimes rather tough starting phase, they are able and willing to contribute a lot. This normally builds a long-term relationship with benefits for both, the clients and your own business.
- The use of control charts in a service environment is possible, although you need to make sure the control chart is set up in the right way, the process owner understands the purpose as well as the usage, and the results are utilised to act upon significant changes in the process.
Summary
- OurBank gained very valuable information about the voice of the clients and their needs as well as the impact of internal processes upon that.
- The team experienced the power of teamwork, communication and process analysis rather than application of complex statistical tools.
- Additional improvement opportunities were identified during the project work, i.e. restructuring the client communication process in other business areas.
