SDP strategy

• Most of us building something like SDP

• With typical continuous improvement budget, this can take years in established companies :(

• Large jumpstart efforts getting funded in some firms - otherwise use MVP

Quick Syntax Utilization Survey

Syntax Proficiency Survey

• Literally - “well advanced in an art, occupation, or branch of knowledge”

• Lee’s definition - ability to understand, test, correct and release someone else’s code

• If not, do you have the budget and foresight to train....

• If not?

Bash

Powershell• Rundeck and Powershell very similar tab

browsability on the command line

• Lots of DevOps project on Windows!

• Modules very similar

• Powershell is verb/noun. I typically do noun/verb, but whatever...

• Would like to see unit test semantics in Powershell.

To the break...• Nothing wrong with well tested imperative

code, convergence does scale better though

• Upside is better participation across organizational boundaries

• Easy to switch between Linux/Windows

• People are part of the solution

• MVP
