Explain what the acronym PMI means in the context of software development.

PMI is an abbreviation for "Primary Manual Inspection" test or "Primary Manual Inspection" process. In the context of software development, PMI usually refers to initial manual testing conducted to verify the basic functionality and core features of an application before automated testing or more in-depth analysis.

This may include:

• Checking main usage scenarios
• Visual inspection of the interface
• Verification of data accuracy

Thus, PMI helps identify obvious errors early on and improve product quality.
