The principles of the Scaled Agile Framework are intended to improve company performance by encouraging lean-agile decision-making across functional and organizational boundaries. 

These principles will influence not only leaders and managers but also all employees and encourage them to change from waterfall thinking to lean-agile thinking. You can also communicate with experts to know more about different SAFe Principles through prettyagile.com/safe-training/

Principle #1: Have an economic perspective

To achieve the shortest possible lead-time, each member of the decision-making process must understand the economic consequences of delays. It is not enough to deliver early and often. 

SAFe states that responsibilities such as sequencing jobs to maximize benefits, understanding economic tradeoffs, and operating within lean budgets must be shared across the company. 

Principle #2: Apply systems thinking

SAFe encourages people to use the framework to apply systems thinking in three key areas: the solution itself; the enterprise that built the system; and the value streams. 

Solutions may refer to products, services, or systems that are delivered to customers, regardless of whether they are internal to the Enterprise or external.

Principle #3 Accept variability; keep options

Designing software and systems are by default an unpredictable task. This principle is addressed by set-based design. It allows for multiple requirements to be retained and provides more options over a longer development cycle. 

The set-based design relies on empirical data to help narrow down the focus on the final design option.

Principle #4 Slow, integrated learning cycles are the best way to build incrementally

Each component of the system cannot be functional. The whole system must also be evaluated to determine if the design options are feasible. To accelerate learning, integration points should be planned in a regular fashion.
