I do masses of laundry, at least one a day and on dry days more as my line can take three/four loads.
Do you have a laundry bag/basket for each member of your family?
Yes, mine are YAs so have their own laundry basket in their rooms, I don't search for laundry so if its not in the basket it doesn't get washed.
I do a load when the individual's basket is full, in the summer its pegged out, on wet days its on my heated airer. Then if it needs ironing it goes in their named ironing basket (folding crate) in my utility room cupboard. If they need something they can find it easily themselves.
Since doing the laundry for each person individually I find I've cut out the whole sorting and then having to find clothes after drying before ironing. It's much easier as everything is already "self sorted" during the whole process.
Towels and bedding get their own separate washes. We all have our own towels as we have our own colours. Same with bedding. There is a lot of bedding as I change beds every week, more often in summer, my Dh lives away from home and brings his bedding home to be washed plus I have a holiday let which creates bedding abd towel washes. Each bed (home and holiday let) has three sets of bedding (one on the bed, one in the wash, one spare ready to go on), I find having three sets less stressful as I know I have a spare somewhere 
Also I have a whites basket in the main bathroom, this is the only basket that has everyone's whites all mixed up ... there aren't many whites with my YAs, mainly Dh has most whites as he wears a t-shirt vest under his shirts.
Shirts for work get washed separately, no fabric softener.
Perhaps you do all the whites on one day and colours on another?
I go by the weather and who has the fullest basket.
Do you iron as and when or all at the same time?
I iron for each person all at once.
I've a press so once set up its best to plough through it while its on. I love tennis so when Wimbledon comes around I allow the ironing to pile up so I can do it while the tennis is on 
Shirts get ironed with my normal iron, the press is a faff for shirts.
Or maybe you pride yourself on not having a set routine?
Can't have the luxury of no routine with a set changeover day for my holiday let it would be impossible.
I've also doubled up on Dh's work wardrobe so his clothes get done during the week so that our precious weekends are not taken up by me turning around his washing.
