The strategic analysis technique called PESTLE evaluates external factors that could impact business performance. The acronym stands for six elements affecting business: political, economic, technological, environmental, legal, and sociological.
PESTLE analysis assesses the possible factors within each category, as well as their potential impact, duration of effect, type of impact (i.e., negative or positive), and level of importance.
This type of business analysis helps stakeholders manage risk, strategically plan and review business goals and performance, and potentially gain an advantage over competitors.

As citizen developers we will probably not be too involved at this level of analysis for most projects but it never hurts to understand how all these areas affect what the business is asking to be done.
