The document discusses process excellence at VFS Global, an organization that manages visa application processes for diplomatic missions. It notes that process management, quality assurance, and process improvement are key to delivering quality service and meeting client expectations. Six Sigma is a major initiative used to support the process excellence framework. The document also presents a project charter to reduce fingerprint override rates in Mumbai from 12% to 7% through a Define, Measure, Analyze, Improve, Control approach led by a team of black belts and green belts.
WQD2011 - Breakthrough Process Improvement - VFS Global - Biometric Overrides reduction
1. Introduction
• Organization Background
– Organization Background : Part of the Zurich based Kuoni Travel Group, VFS Global was established
in 2001, in Mumbai India, as a specialist partner for diplomatic missions worldwide. VFS Global
serves diplomatic missions by managing all the administrative and non-judgmental tasks related to
the entire lifecycle of a visa application process, enabling diplomatic missions to focus on the key
tasks of assessment and interview.
– With an employee strength of 4000 (+), as on date, VFS serves diplomatic missions of 35 countries
through its 425(+) offices and has operations in 52 countries across 5 continents. and processes in
excess of 36 million visa applications (contracted) annually.
• Process Excellence at VFS Global
– Process excellence is at the core of our business; the objectives being to deliver quality and value
add to our customers (applicants) and clients (Embassy), improve productivity and ensure consistent
performance of processes. It is critical to provide the agreed level of service to our client (UK
mission) and not only meet but also exceed clients’ expectations.
– Process Management, Quality Assurance and Process Improvement are the three key components of
the process excellence model and Six Sigma is one of the major initiatives contributing to the overall
framework in the Organization since March 2008. This framework is supported by a team of over 80
YB (Yellow Belts), 25 GB (Green Belts) and team of 3 Black Belts (BB) comprising of people having
relevant Process Excellence experience and certification from various companies .
– A robust governance process, the Business Quality Council (BQC) ensures the prioritization and
successful delivery of the identified initiatives.

2. Project Charter D M A I C
Business Case
UK Visa had come up with the process of capturing fingerprints for secure immigrations. This is an extremely critical step as it becomes a bypass
to Immigration Safety measures and failure (override) could result in fraud, terrorist activities and other grave security concerns in UK. By reducing
the overrides it not only does it improve Mission/applicant satisfaction but would result in significant savings to VFS Global due to rework reduction.
Problem Statement Milestone
Based on Sep ’10 to Nov ’10 overrides data in Mumbai Visa Application Define Dec 13, 2010
Center’s (VAC) it was at around 12% on an average which is too high and it
defeats the purpose of Biometrics Enrolment as it becomes a bypass to Measure Jan 07, 2011

9. Quick Wins D M A I C
In case of overrides the data was captured manually on 9
Current Process sheets of paper by the staff. This additional activity
contributed to nearly 5 mins/ override
Proposed Solution To have a drop down included in the software itself with the
most frequent reasons for overrides.

1. NVA step reduced which resulted in nearly savings of 4
Benefits minutes/override
2. Real time report extraction resulted in more focus.

Learning
• Process Learning : Putting more focus on those overrides cases which are happening because of dry hand,
moist hand , old age applicant, child below 5~7 years age group. Learning shared with all VACs across the
globe.
• Change Management: Mission resistance observed initially when suggested the need for a maintenance
plan for the Biometric machines. Mission agreed for a regular machine maintenance & replacement
• People Management: Inconsistency observed in the number of attempts made by the staff to capture the
biometric. SOP designed and Internal Audits conducted to ensure adherence
Team Recognition
• Client Recognition: Team received appreciation from Mission for taking the initiative to reduce overrides
• Internal management Recognition : The project bagged the an internal award from the Process Excellence
(received from the management) in the Quarterly Quality Summit
• Case study published in the Quarterly company newsletter

19. Summary
A.Methodology Used- DMAIC
B.Please indicate why this project is an excellent improvement example.
Biometrics is a relatively new concept introduced by a few missions in the Visa processing process. It is also a
very critical step in ensuring secure immigration. More missions are in the process of including biometrics in
their Visa processing process .The project aimed at reducing the overrides (Overrides are the occasion when
three attempts have been made to take fingerprint to the standard required, but all three attempts fail the
system threshold for quality) from 12% to <7%.. The improvement project helped in ensuring better scores
from missions & saving penalties. Moreover, the best practices could be successfully deployed for other
missions thereby, ensuring secure immigrations. The improvements realized from this project have been
globally applied attracting appreciations from mission helping us gain competitive advantage.
