Some times a losing team needs to rebuild - and that rebuilding includes getting rid of poor performers.
Sometimes a store has to trim good selling products from its shelves, so it can concentrate the brand name on what it does well.
Pruning makes a plant smaller. It also encourages future growth.
How's that worked out so far for the Detroit Lions or the Kansas City Royals? Or even better, the Atlanta Falcons. At one time the Falcons had a rookie QB that they just didn't think wouldn't make it in the NFL or help to bolster the winning percentage of their failing team, so they traded him. Four games later, that Quarterback went on to start every game for the next 16 years. I wonder how Brett Favre felt about it at the time.

I'm assuming you mean "poor selling products", but be that as it may. Grocery stores are a great example. I'm glad you brought it up. Take Proctor and Gamble. P&G makes about 4 different brands of laundry soap. Why? Because of shelf-space. P&G makes and markets those different brands to different constituents all in the effort to advance the corporation and the corporation's agenda. Now, they're all P&G brands, but they're just a little different from each other to accommodate a diverse customer base. Is there a lesson there?

And sometimes a plant is pruned to such an extreme degree that it just dies. It just shrivels up and dies and becomes an irrelevant stump in the garden in which in previously flourished.
Analogies can be so perplexing.
