What Are HowTo’s

A HowTo is a document that does precisely what the name suggests i.e. It’s describes “HowTo” achieve a set of outcomes through illustration of all the steps involved. HowTo’s are generally structured and written without too much technical jargon in a straight forward manner without making too many assumptions of the depth of knowledge the reader. HowTo’s are meant to make for easy reading and are logical in the sequence of steps it recommends.

Any background knowledge required to assimilate the information provided in the HowTo is generally highlighted at the start of the HowTo. HowTo’s are generally written for the professional who are clear of what they need to accomplish but have little or no knowledge of how to go about achieving those objectives. HowTo’s are meant to be exhaustive in nature and they are definitely not meant to offer the most efficient way of getting the job done. A HowTo should be seen as a kick starter that helps the user get up and running with a given task without having to master all the required fundamentals.

 Why HowTo’s @ PPA?

HowTo’s have been the mainstay of the Open Source and Free Software movement for decades. One of the reasons why Open Source and Free Software is so widely used today is simply because of the depth of documentation that exists and the maturity of the Open Source ecosystem which has delivered scalable, open and reliable software. HowTo’s like many other building blocks have helped the Open Source and Free Software movement grow immensely while eliminating the need to keep re-inventing the wheel. It’s only natural that we at Practical Performance Analyst adopt the best from the Open Source and Free Software movement. A lot of the work we do at Practical Performance Analyst borrows from the fundamentals of the Open Source movement and HowTo’s are definitely one of them.

As HowTo’s @ PPA grows and matures we will hopefully reduce the reinventing of the wheel which happens so very often at organizations, projects and programs when it comes to the science of building/delivering systems that scale.
