was innovative at the time, because to consider the "response" you wanted from the consumer first, ahead of the messaging, was a new thought.
Nicholas Pevsner, the chronicler of great and ancient British buildings, described it as "Originally a C15-C16 timber framed hall house with solar cross-wing, the latter mostly rebuilt to a large T-plan
with shaped gable end for John Collins, 1678."
in the T-Plan methodology product drivers are examined in the market section, not the product section like above (Phaal et al., 2001).
For the rapid introduction of TRM, a method called T-Plan Fast Start Process (Phaal et al., 2001) is widely used in the international practice and it was also suitable for the projects we had.
This article focuses on how the "fast-start" T-Plan method (2,3,4) can be customized to fit a wide range of organizational contexts, in terms of both roadmap architecture and process.
Following a brief overview of the T-Plan process, we illustrate the principles that enable roadmapping to be customized with six generic case study examples.
Thus the home of a worker might change from the rectangular miner's cabin to the T-plan
cottage to the pyramidal-roofed cottage.
A dissection D is called a T-plan  if each junction point where a vertical line meets with a horizontal line is a T-junction.
The [delta]-transform satisfies some of these requirements but has the problem that it may convert a T-plan to a non-T-plan, in general.
This article describes a process called T-Plan, which has been developed to support the rapid initiation of roadmapping and thereby address these challenges (7).
Coordination is a key element of the T-Plan approach, with the need to ensure that the process is continually aligned with company needs (coordination points are included between each step), as the results from each workshop cannot always be predicted in advance.
