Advances in machine learning (ML) algorithms and increasing availability of computational power have resulted in huge investments in systems that aspire to exploit artificial intelligence (AI), in particular ML. AIenabled systems, software-reliant systems that include data and components that implement algorithms mimicking learning and problem solving, have inherently different characteristics than software systems alone. 1 However, the development and sustainment of such systems also have many parallels with building, deploying, and sustaining software systems. A common observation is that although software systems are deterministic and you can build and test to a specification, AI-enabled systems, in particular those that include ML components, are generally probabilistic. Systems with ML components can have a high margin of error due to the uncertainty that often follows predictive algorithms. The margin of error can be related to the inability to predict the result in advance or the same result cannot be reproduced. This characteristic makes AI-enabled systems hard to test and verify. 2 Consequently, it is easy to assume that what we know about designing and reasoning about software systems does not immediately apply in AI engineering. AI-enabled systems are software systems. The sneaky part about engineering AI systems is they are "just like" conventional software systems we can design and reason about until they?re not.
