Process

Code can express what we want to accomplish, but it’s a little more difficult to express why we’re doing something in the first place. The people who maintain code are often not those who originally wrote it, so documenting why helps set a context and gives clues as to what the author was thinking when they came up with a particular design, making developers' jobs easier.

IoT security is a large and changing topic, but there is one basic starting point where device security can be improved during development and testing: the user interface. The UI should be the first line of defense, but it’s currently weak in most IoT devices. Implementing better practices during the initial UI setup will go a long way toward improving security.

Test coverage is a strategy to help us spend scarce testing time on the right priorities. When things were tested last, how much automation coverage we have, how often the customers use the feature, and how critical the feature is to application are all factors to consider. Here are some ideas for keeping quality high when you're transitioning to continuous delivery.

Developers have so much to do that unit tests often fall by the wayside. One solution is to train testers to handle them. Testers get involved earlier in the development lifecycle, they can enhance their programming skills, and bugs are found and fixed quickly and easily, reducing the functional testing phase. Consider taking an active role in unit testing.
