Case Study - TFA

The Client

Toyota Finance Australia Limited (TFA) commenced operations in 1982. Today, the company is recognized as one of the nation's leading financiers with net receivables exceeding $4.3 billion, a Moody's Long-Term Debt Rating of AA1 and a Standard & Poor's rating of AAA.

The Situation

The residual value of a leased vehicle is one of the main parameters in determining the lease terms for a TFA customer. This value was calculated manually by TFA's Group Analytics Department using Excel spreadsheets. With over 70,000 unique vehicle models, this was a very tedious and time consuming process. Furthermore, the lack of an automated calculation process and a direct interface to the central data repository resulted in a high possibility of data inconsistency and human errors.

The Solution

Infinity Technologies was engaged to provide an automated solution for the residual value calculation. With over 5 million residual value records in the master database and a constantly changing model lineup, performance and flexibility were the key considerations. The Residual Value Upload Automation System was custom developed by Infinity in Microsoft .NET.

Featuring a SQL Server backend, it performs 7 major types of calculations and is integrated directly with the master residual values database. The results from this system are now used by TFA to generate more than 400 customer quotations every day.

What the client said about us

"We definitely made the right decision in choosing Infinity Technologies.

The team immediately impressed us with their skills and experience and their ability to understand and design a solution for our needs. Throughout the project, they kept us informed at all times and we did not have one single communication issue.

The system is easy to use and exceeds all of our performance specifications. The residual value upload process used to take up 1 to 2 weeks each month, but it was reduced to 1 hour with the implementation of the system, which has greatly improved the efficiency in the allocation of human resources. The automated error checking mechanism included in the system has reduced the chances of making human errors which is highly critical to the management of the business. We are particularly impressed by the quality of the system testing performed by Infinity which made the UAT process performed by us highly efficient in terms of time and effort.

The system has now become a valuable asset of TFA and we could not be happier with it. We will definitely choose Infinity Technologies again for our future projects."
