Commercial Custom
Fast Time to Market More features less price

Flexible to plug in Proprietary and good for
accessories after sales
Not optimized for price Need a good team for
and size handling after sales
Already tested and field Custom Fit Solution

9. Different ways to manage development
Different companies manage development activities in different ways. This is based on the
company strategy, development complexity, investment criteria, technology involved and
resources available.

10. Choosing the right design partner
Expertise to develop the technology within the discussed time frame. Preferably
companies with matured Intellectual Property or field proven products give a clear
demonstration of their ability to handle the development activity.
Familiarity with the fine design elements like processor, algorithms, timing, sensor
interfacing, control elements, alerting mechanism, etc
Having the domain expertise in-house or guided by experts from the machine builder
or advisor.
Ability to integrate the custom hardware into the machine and working with the
debug/engineering/quality team in house to address run time issues.
Inclination to update and maintain embedded hardware and software subsequent
releases.
High Integrity on non-disclosure agreements.

early stage to help in creating
specifications to supporting the
finished product and working
with their engineers to intergrate
in their machine
