The standard way to assure functional design is to review the description of a module. If the description includes conjunctions such as "and" or "or", then the design has more than one responsibility, and is therefore likely to have side effects. The responsibilities need to be divided into several

of an object where the parameters are tied to real-world design criteria, such as an axle that will adjust its diameter based on the strength of the material and the amount of force being applied to it in the simulation. It is hoped that this will create efficiencies in the design process for

Some functions inherently have mixed semantics. For example, a function "move the car from the garage" inherently has a side effect of changing the "car position". In some cases, the mixed semantics can extend over a large topological tree or graph of related concepts. In these unusual cases,

Since maintenance is more than 3/4 of a successful system's life, this feature is a crucial advantage. It also makes the system easier to understand and document, which simplifies training. The result is that the practical lifetime of a functional system is longer.
133:
design assures that each modular part of a device has only one responsibility and performs that responsibility with the minimum of side effects on other parts. Functionally designed modules tend to have low

The advantage for implementation is that if a software module has a single purpose, it will be simpler, and therefore easier and less expensive, to design and implement.

In a system of programs, a functional module will be easier to reuse because it is less likely to have side effects that appear in other parts of the system.

to different modules. For example, most systems have an "initialization" section that starts up the modules. Other well-known examples are the
