QFD and reengineering of New Product Development process: the Tetra Pak experience
Track: I2
Abstract:
In 2000, Bocconi University School of Management and Tetra Pak carried a joint research
program on QFD best practices and tools, in order to methodologically support the
on-going implementation of QFD within the company.
This paper aims to describe the QFD project run by Tetra Pak within a wider program of
reengineering of their NPD process and to summarise the main evidences from this
experience.
Tetra Pak is one of the world's largest suppliers of packaging systems for liquid food,
in particular filling equipments for long shelf life-non-refrigerated liquid food.
As Tetra Pak covers all the packaging process, their products have to take in
consideration the needs of a double type of users: the direct customer producing the
packages through the filling equipments and the final consumer who buys the package.
In order to face an increasingly competitive market over the last few years, Tetra Pak
is shifting to a process oriented organization, to grant the alignment to common
objectives and increase flexibility, and achieve a market driven strategy in concurrent
with the product driven strategy historically pursued.
In this context, the company adopted the QFD as an innovative marketing/design approach
to analyse the "voice of the customer" as well as a new way to structure the
communication flow from product management to development.
The implementation of QFD started with one pilot study on family packages and two market
researches on 0.5 liter sport drink packages and 1 liter milk packages. The researches were
conducted on the final consumers as teenagers for the 0.5 liter package, households and
purchase responsible for the 1 liter family packages.
All the survey were focused on three main topics: the understanding of the target's
needs and expectations (mainly through qualitative market researches); the target
perception of quality through the definition of a representative benchmark
(with interviews on a larger sample basis); the set-up of an in-house measurement
system to clarify the relationship between consumer's perception and product features
and to objectively quantify the performance of these features.
The QFD methodology proved to be very powerful for all that concerns "functionality",
providing an effective evaluation of technical feasibility related to the market
requirements. It contributed to the definition of a standardized approach to market
researches, which enables to follow up projects on a concrete basis and to compare
results from market researches carried out at different times. Otherwise, as frequently
affirmed by the literature, the Tetra Pak experimentation of the QFD confirmed the
weakness of the tool in the evaluation of the emotional needs (such as "image" or
"appeal") and its inadequacy in the capture of the customer unexpressed requirement.
The paper ends with the presentation of the progress of the Tetra Pak project, aiming
to the building up of an appropriate "gemba" for any future market research.
