1 . A system comprising:
a computing device comprising:
one or more processors; and
data storage storing processor-executable instructions, wherein execution of the processor-executable instructions by the one or more processors causes the one or more processors to:
guide a user through a test strip image capture procedure on the computing device;
perform an evaluation of an image of one or more test strips captured during the test strip image capture procedure after the one or more test strips have been exposed to a cleaning process;
generate an assessment of a performance of the cleaning process based on the evaluation, the one or more test strips including a carrier and an indicator operable to change as a function of the cleaning process;
select an action plan based on the assessment; and
generate, for display on the computing device, the action plan selected based on the assessment.
2 . The system of claim 1 , wherein:
the one or more test strips include a plurality of indicators, wherein for each respective indicator of the plurality of indicators, the respective indicator corresponds to a respective parameter of a plurality of parameters of the cleaning process, the respective indicator is configured to change color independently of other indicators of the plurality of indicators as a function of the respective parameter corresponding to the respective indicator, and
the one or more processors are configured to, as part of evaluating the image, determine color changes of the plurality of indicators.

presence and/or concentration of an anionic, non-ionic, or cationic tenside,
presence and/or concentration of a corrosion inhibitor,
presence and/or concentration of a polymer,
presence and/or concentration of a biocide, or
a combination of one or more other parameters.
8 . The system of claim 1 , wherein the action plan comprises one or more of:
advice to increase or lower a detergent concentration,
advice to increase or lower a temperature,
advice to increase or decrease a process time,
advice to use a different detergent, or
advice to change a water quality parameter.
9 . The system of claim 1 , wherein:
the computing device further comprises a camera, and
the test strip image capture procedure comprises docking the computing device in an imaging box having a housing that defines a camera aperture configured to be aligned with the camera, the housing further comprising or defining a test strip slot configured to hold one or more test strip holders configured to hold the one or more test strips during image capture.
10 . The system of claim 9 , further comprising the imaging box.
11 . The system of claim 1 , wherein the computing device is a mobile phone device.
12 . A method comprising:
outputting, by one or more processors of a computing device, for display on the computing device, guidance to guide a user through a test strip image capture procedure on the computing device;
performing, by the one or more processors, an evaluation of an image of one or more test strips captured during the test strip image capture procedure after the one or more test strips have been exposed to a cleaning process;
generating, by the one or more processors, an assessment of a performance of the cleaning process based on the evaluation, the one or more test strips including a carrier and an indicator operable to change as a function of the cleaning process;
selecting, by the one or more processors, an action plan based on the assessment; and
generating, by the one or more processors, for display on the computing device, the action plan selected based on the assessment.
13 . The method of claim 12 , wherein:
the one or more test strips include a plurality of indicators, wherein for each respective indicator of the plurality of indicators, the respective indicator corresponds to a respective parameter of a plurality of parameters of the cleaning process, the respective indicator is configured to change color independently of other indicators of the plurality of indicators as a function of the respective parameter corresponding to the respective indicator, and
evaluating the image comprises determining color changes of the plurality of indicators.
14 . The method of claim 13 , wherein the one or more test strips includes a plurality of test strips, each test strip of the plurality of test strips including two or more indicators of the plurality of indicators.
15 . The method of claim 13 , wherein the one or more test strips consists of a single test strip.
16 . The method of claim 13 , wherein the one or more test strips includes a plurality of test strips, each indicator of the plurality of indicators being included in a different test strip of the plurality of test strips.
