I also have a "launchpad" system set up to help us keep organized and get out of the door on time. I have two coat hooks (one for DD and one for me) and a storage unit close to the front door. It has 4 'cubes' - two for DD9, two for me. I also have our calendar and a weekly whiteboard hung on the wall over the unit, so I can see all future appointments/events but also see at a glance what we have planned that week specifically.
During term time one of DD's cubes is for her school bag and shoes only - they live in that cube, so unless she's actively doing her (minimal) homework her school bag should be in the storage unit and as soon as she walks into the house, her school shoes go into the unit and her coat gets hung up on her hook and not lying on the floor for me to fall over and I can see straight away if they aren't there. The other cube is for anything she needs for any given day/activity. So on Mondays she has swimming, so Sunday night her swimming bag should be in the cube; on Thursday she has dance class so her dance bag should be there by Wednesday night etc.
DD knows that all of the stuff she needs for the following day should be in her launchpad before she goes to bed so that the following morning we can grab and go. There's always the odd misplaced/forgotten item but since we introduced this system those instances are very few and far between as it's just routine to make sure everything is in the unit.
My first cube is my dumping ground for bits and bobs - reciepts, spare change, keys, bag etc - all get dumped in a basket on this shelf so that I know where it is without searching and every so often I give it a clear out and put everything away properly. The second cube is like DDs and is for anything I need to take with me on a given day - so if I'm going to the library, I will leave my tote with the library books in the cube; if I'm going grocery shopping I leave the reuseable bags in there; if I'm going to the gym after work, I'll leave my gym bag there etc.
On the top of the unit I have a small "letter organizer" with two slots - on for incoming and one for outgoing mail. So if there's a birthday card I need to drop off, a bill I need to pay, a letter I need to drop in the mail, or a permission slip DD needs to take back to school it will be in the outgoing slot ... if DD has brought home a letter/invite or the post has finally arrived at 3pm, as I'm about to leave the house to pick up DD from school, and I don't have time to deal with it right away, it goes into the incoming slot and I know exactly where it is when I finally get a minute to sit down and open/action it.
