IoT projects are typically complex: New technology, too many standards,

requirements may change.

In pure software projects, agile methodologies are well established.

Regarding mixed hw/sw projects, reconsideration is necessary.

Developing IoT devices typically requires multiple teams with different

knowledge backgrounds.

Mock-ups are for testing of intermediary artifacts. Prototypes can be

manufactured parallel to development.

Prototype

A prototype is a manufactured sample of the product,

based on the current development state. It is

produced in a way that is as close as possible to the

final manufacturing process.

Mockup

A mockup is a model of a part or the complete

product, used for demonstration, evaluation and

other purposes. For a mockup, certain parts of the

product may be simplified in order to demonstrate or

evaluate specific details.

Example: Development Boards, Cardboard Boxes

Teams work agile within stages defined by product management.

Continuous integration is essential all the while. Make sure parts fit together.

Take away & outlook

IoT ▪ projects can benefit from developments and

knowlegde within the internet industry. Agile

methodologies are worthwhile.

Test ▪ automation is an essential driver for accelerated

development processes. It strengthens trust in the

process and in quality of artifacts.

Communication ▪ and cooperation between teams is vital.

We▪ depicted a blue print. Each company should find its

own methods and optimize them according to their

needs.
