I use techniques like MoSCoW, Kano model, Value vs Effort matrix, WSJF, and Cost of Delay to prioritize the backlog.

• MoSCoW method - Must have, Should have, Could have, Won't have

• Kano model - Basic needs, Performance needs, Excitement needs

• Value vs Effort matrix - High value, Low effort items are prioritized

• WSJF (Weighted Shortest Job First) - Calculating priority based on cost of delay and job size

• Cost of Delay - Prioritizing based on the impact of delaying a task

• OOPS focuses on creating objects that interact with each other to solve a problem

• Key principles include encapsulation, inheritance, polymorphism, and abstraction

• Encapsulation: bundling data and methods that operate on the data into a single unit

• Inheritance: allows a class to inherit properties and behavior from another class

• Polymorphism: ability for ob...read more
