How do you test and document manufacturing?

1 Testing methods

Testing methods are the techniques and procedures used to verify and validate the performance, functionality, and reliability of manufactured products or components. Destructive testing, for instance, involves applying extreme stress, temperature, pressure, or force to a sample or a part to evaluate its strength, durability, or failure mode. Examples include tensile, impact, fatigue, or hardness tests. Non-destructive testing involves inspecting or measuring a sample or a part without damaging or altering it; examples include visual, ultrasonic, magnetic, or radiographic tests. Functional testing checks if a product or a component meets its intended specifications and requirements; electrical, mechanical, or environmental tests are examples of such. Statistical process control monitors and analyzes the variation and quality of a process using statistical tools and charts; control charts, histograms, or Pareto charts are examples of this.

2 Testing tools

Testing tools are the equipment and software used to perform and automate the testing methods. Test fixtures, such as clamps, grips, or jigs, can be used to hold, position, or apply force to a sample or a part during testing. Test instruments like meters, gauges, or oscilloscopes are utilized for measuring, recording, or displaying the physical or electrical properties of a sample or a part during testing. Additionally, test software programs such as LabVIEW, MATLAB, or Excel can be employed to control, analyze, or report the testing data and results.

3 Documentation methods

Documentation methods are the ways and formats of recording and presenting the testing information and outcomes. Test plans, for example, are documents that describe the purpose, scope, objectives, and procedures of a testing project, as well as the test criteria, resources, schedule, and risks. Test reports summarize the testing results, analysis, and conclusions with test data, graphs, charts, and recommendations. Test procedures provide the detailed instructions and steps for performing a specific test including the test equipment, settings, parameters, and safety precautions. Lastly, test cases define the input, output, and expected outcome of a specific test scenario along with the test conditions, assumptions, and verification methods.

4 Documentation tools

Documentation tools are the software and applications used to create and manage the documentation methods. Popular tools include word processors such as Word, Google Docs, or LibreOffice Writer; spreadsheets like Excel, Google Sheets, or LibreOffice Calc; databases such as Access, MySQL, or SQLite; and document management systems including SharePoint, Dropbox, or Google Drive. These programs enable users to write, edit, format text documents; organize, calculate, and visualize data in tables and charts; store, retrieve, and manipulate data in structured and relational formats; and store, share, and collaborate on documents in a centralized and secure location.

5 Testing best practices

Testing best practices are the guidelines and standards that help you to plan, execute, and document your testing activities effectively and efficiently. It's important to define testing objectives and criteria realistically, as well as choose the right testing methods and tools for your needs and budget. Additionally, you should follow testing procedures and instructions carefully, document testing data and results accurately, analyze data objectively and critically, and communicate findings and recommendations clearly.

6 Documentation best practices

Documentation best practices are essential for creating and maintaining the quality and usability of your documentation. To ensure your documentation is consistent and professional, use a standard format and style. Additionally, use clear and concise language, avoiding jargon and ambiguity. Visual aids, examples, references, citations, version control, revision history, feedback, and review can also help you illustrate points, support sources and claims, track changes and updates, and improve your documentation.
