Understanding software development through everyday analogies

๐ŸŒฑ

Software Development Life Cycle (SDLC)

๐ŸŒฑ Garden Growing Process

SDLC is like growing a garden - you plan what to plant, prepare the soil, plant seeds, water and tend them, then harvest the fruits.

๐Ÿ‘ถ For Kids: Like following a recipe to bake a cake - each step must be done in order to get a delicious result!

๐Ÿ“

Requirements Gathering

๐Ÿ“ Wish List Creation

Requirements are like making a detailed wish list for your dream house - exactly what rooms you want, colors, and features.

๐Ÿ‘ถ For Kids: Like telling your mom exactly what you want for your birthday party - decorations, games, and food!

๐Ÿƒโ€โ™‚๏ธ

Agile Development

๐Ÿƒโ€โ™‚๏ธ Sprint Racing

Agile is like running short sprints instead of a marathon - you run fast for a short time, rest, check progress, then sprint again.

๐Ÿ‘ถ For Kids: Like building with LEGO blocks - you build a small part, show it to friends, get feedback, then build the next part!

๐Ÿ”

Testing & Quality Assurance

๐Ÿ” Detective Investigation

Testing is like being a detective who investigates the software to find any bugs or problems before users see it.

๐Ÿ‘ถ For Kids: Like proofreading your homework before turning it in to catch any mistakes!
