Corporate memory is like a big book where a company writes down all the important things that happen. This helps the company remember what they did before, what worked and what didn't work, and how they can do things better in the future.
Imagine you and your family are going on a vacation to the beach. Your mom and dad will make a list of things you need, like sunscreen, towels, and beach toys. They will write it down so they don't forget anything. This is like the company writing down important information so they don't forget.
In a company, corporate memory could include things like how they made a successful product or how they solved a difficult problem. This memory is important because it helps the company learn from its mistakes and successes. Just like when you fall down and hurt yourself, you learn not to do that again in the future.
Sometimes people in the company might leave or retire, but by having a corporate memory, the company still remembers what they did and can use that knowledge to keep growing and improving.
