LAUNDRY-OPSPREMISE

A load of laundry per day will give us free Sundays

LAUNDRY-OPSPREMISE


We will have more opportunity for family fun

@behemphi

LAUNDRY-OPSPREMISE


We will have more opportunity for family fun

Stress around laundry will decrease

@behemphi

LAUNDRY-OPSLESSONS LEARNED

Needed to think differently about when to do a load. (batch size)

@behemphi



Needed to think differently about special situations (trips)

@behemphi



Needed to think differently about special situations (trips)

We have way too many clothes

@behemphi

LAUNDRY-OPSEVOLVED

Often more than one load per day

@behemphi

LAUNDRY-OPSEVOLVED


Often a very small load on a day

@behemphi

LAUNDRY-OPSEVOLVED


Often a very small load on a day

Easier to share work

@behemphi

LAUNDRY-OPSDEVOPS

Adoption of CD is first about how you view batch size

@behemphi

LAUNDRY-OPSDEVOPS


Missing a Sunday of laundry was terrible, missing a day is a non-event

@behemphi

Tools only matter after you have an operational model

@behemphi

LAUNDRY-OPSDEVOPS



Tools only matter after you have an operational model (low water, low energy washer/dryer help control cost)

There was a stunning amount of spare capacity in our laundry system. You can see it in the SDLC

CLOSET-OPSPREMISE

Clothes are cash tied up in our closet

@behemphi

CLOSET-OPSPREMISE


Features are cash tied up in source control

@behemphi

CLOSET-OPSPREMISE


Features are cash tied up in source control

Features are a competitive advantage

@behemphi

CLOSET-OPSLESSONS LEARNED

Our closets were overflowing (> $15k in clothing in our house!)

@behemphi



Fast growing kids shouldn’t have two weeks worth of clothes

@behemphi



Fast growing kids shouldn’t have two weeks worth of clothes

We have bought about 2/3 less clothing this year

@behemphi

CLOSET-OPSEVOLUTION

More room in our closets means ability to store stuff at home (not renting storage space)

@behemphi

CLOSET-OPSEVOLUTION

Think about clothing purchases (when/why) differently. More likely to buy one thing on sale.

@behemphi

CLOSET-OPSDEVOPS

6 people~ $1m per year. Quarterly Release -> $250k in source control

@behemphi

CLOSET-OPSDEVOPS


If features get to market faster, they can be exploited faster (new sales, up sales, better cash flow in/out)

You won’t take the risk with your laundry/closet.

PM wanted AM involved, AM brought customer

@behemphi



Customers were thrilled

@behemphi




Site launch was non-event

@behemphi





Updates became trivial

SUCK-OPSPREMISE

Automating vacuuming would put time back in each day

@behemphi

SUCK-OPSPREMISE

Automating vacuuming would put time back in each day

Daily vacuuming would decrease allergy issues in the house

@behemphi

SUCK-OPSEVOLUTION

Expected to want to further automate but have not

@behemphi

SUCK-OPSEVOLUTION

Expected to want to further automate but have not

Kids often take care of this.

@behemphi

SUCK-OPSLESSONS LEARNED

There is little enough pain in moving the towers and vacuum.

@behemphi

SUCK-OPSLESSONS LEARNED

There is little enough pain in moving the towers and vacuum.

Sometimes quality can be achieved by repetition rather than explicit effort. (Fight forward)

Still need our old vacuum for special situations

@behemphi

SUCK-OPSDEVOPS

Our house is single story, and all wood/tile. Perfect situation for this tool

@behemphi

SUCK-OPSDEVOPS


Our kids are good about picking up the floor (culture)

@behemphi

SUCK-OPSDEVOPS



The tool is usable by all of us. Removes need for low value skill.

The tool is important, but it is the process that actually matters

@behemphi

Moving from a home grown system to a tool (Chef), allowed a 5 person company to service 70 customers, 200 machines

The reason Chef was the right tool was not Chef, it was our single tenant architecture.

@behemphi

SUCK-OPSREAL WORLD

Automating the dev environment fostered collaboration

Site launch and update a non-event due to repetition

Saved 8 hours per dev per week.

@behemphi

PAINT-OPSPREMISE

Lessons from Laundry should apply to painting the interior of our house

@behemphi

PAINT-OPSPREMISE


Lower stress of home improvement

@behemphi

Lower stress of home improvement

Increase innovation (try various colors and techniques)

@behemphi

PAINT-OPSEVOLUTION

Started with outcome goals (e.g paint this wall)

@behemphi

PAINT-OPSEVOLUTION

Started with outcome goals (e.g paint this wall)

Ended with time based goals (e.g. I have 3 hours on Thursday)

@behemphi

PAINT-OPSLESSONS LEARNED

Set-up/Tear-down costs (time) were expected to be very high. Only about 25% of expected value. (Kids help!)

Time vs. feature based batching substantially lowered stress.

@behemphi

PAINT-OPSDEVOPS

Setup cost akin to inserting a feature flag in the code.

@behemphi

PAINT-OPSDEVOPS


Friends curiosity about progress translates to transparency of change

@behemphi

PAINT-OPSDEVOPS



Overall increase in time offset by our willingness to paint again soon

Overall increase in time offset by our willingness to paint again soon

Find wife painting while dinner was cooking akin to enabling others to do high value work.

Some times showing the customer the unfinished product is awesome

@behemphi

LEGO-OPSPREMISE

My sons and I could not build a 4ft, 20k piece Lego Pyramid in 5 hours.

By organizing the project so that anyone could contribute, we would get done.

@behemphi

LEGO-OPSEVOLUTION

Project has been attempted for 4 years.

Successful at 3ft last year and 4ft this year

We will go for 5ft next year.

@behemphi

LEGO-OPSLESSONS LEARNED

Regularity of methodology is critical

Something as simple as blue and white stripes can have a huge effect on quality.

Evolving work roles is critical

Engaging everyone is key to success

Allowing children to become managers is surprisingly effective. Its about personality, not age.

@behemphi

LEGO-OPSDEVOPS

Model for open source software.

Quality is critical at every stage of the project.

Level of buy-in on quality with each helper determines role (e.g. 3yr old collects the right bricks but does not build)

Identifying and elevating people who own the process and its evolution drives success

@behemphi

LEGO-OPSREAL WORLD

Ensure quality processes are in place before starting is critical to the success

Ensure processes for building and deploying software are in place is critical to success

Engineers who do not own the customer experience are not worth keeping.

Automating quality and build from day one allowed a team of three to accomplish what a team of 12 could not.
