● Devops is a growing professional and cultural
movement
● We don't have all the answers yet
● We are reaching out to different communities
● We will point out problems we see..
● Only the name is new

While we are still working out the solutions

● Adopt the new philosophy. We are in a new economic age. Western management
must awaken to the challenge, must learn their responsibilities, and take on leadership
for change.
● Cease dependence on inspection to achieve quality. Eliminate the need for massive
inspection by building quality into the product in the first place.
● Improve constantly and forever the system of production and service, to improve
quality and productivity, and thus constantly decrease costs.
● Institute training on the job.
● Institute leadership The aim of supervision should be to help people and machines and
gadgets do a better job.
● Drive out fear, so that everyone may work effectively for the company.
● Break down barriers between departments. People in research, design, sales, and
production must work as a team, in order to foresee problems of production and
usage that may be encountered with the product or service.
● Eliminate slogans, exhortations, and targets for the work force asking for zero defects
and new levels of productivity. Such exhortations only create adversarial relationships,
as the bulk of the causes of low quality and low productivity belong to the system and
thus lie beyond the power of the work force.

●
Eliminate management by objective. Eliminate management by numbers
and numerical goals. Instead substitute with leadership.

●
Remove barriers that rob the hourly worker of his right to pride of
workmanship. The responsibility of supervisors must be changed from
sheer numbers to quality.

●
Remove barriers that rob people in management and in engineering of
their right to pride of workmanship.
● Institute a vigorous program of education and self-improvement.
● Put everybody in the company to work to accomplish the transformation. The
transformation is everybody's job.

#monitoringsucks
Monitoring is AWESOME. Metrics are AWESOME. I love it. Here's what I don't love:

● Having my hands tied with the model of host and service bindings.

● Having to set up "fake" hosts just to group arbitrary metrics together

● Having to either collect metrics twice - once for alerting and another for trending

● Only being able to see my metrics in 5 minute intervals

● Having to chose between shitty interface but great monitoring or shitty monitoring but
great interface

● Dealing with a monitoring system that thinks IT is the system of truth for my
environment

● Not actually having any real choices
