| DFSS
(Design for Six Sigma) |
|
DFSS (Design for Six Sigma) is used to
design a new product or service, or to start
from scratch with an existing process or
service. This contrasts with the normal
Six Sigma process that is used to improve
an existing process or service.
For example if you wanted to replace a
manual accounting system with a computer-based
one then you might use DFSS.
Similar to DMADV with the addition of the
'optimize step':
| Define |
Define the project
objectives, similar to DMAIC. |
| Measure |
Measure the expectations
of all the stakeholders, particularly
the customers. Also use benchmarking
and competitor analysis. |
| Analyze |
Identify and analyze
the alternative solutions |
| Design |
Carry out the detailed
design |
| Optimize |
Use experimental
design, simulation etc. to optimize
the solution |
| Verify |
Verify the design
through pilot studies and then evaluation
as it goes into service |

Five Forces Analysis |
|
A type of competitive analysis
based on:
| Bargaining Power
of Customers |
| Bargaining Power
of Suppliers |
| Threat of New Entrants |
| Threat of Substitute
Products |
| Competitive Rivalry |
A Type of Analysis that compares the benefits
of alternative solutions. It uses a matrix
approach:

The alternative in the first column is
allocated a '0' in every category. If an
alternative is better in that category it
is given a '+1', if worse '-1'
TRIZ was developed in the former USSR and
TRIZ is the acronym for a russian description
that translates as the 'Theory of Inventive
Problem Solving'.
It is based on the idea that problems
and their solution are repeated across all
industries, in other words designers are
constantly 'reinventing the wheel'. TRIZ
attempts to invention into a systematic
method by reducing it into a series of principles.
