3 NEWTON'S LAWS OF SOFTWAREDEVELOPMENT

THE SYSTEM BEING PRODUCED WILL TEND TO HAVE ASTRUCTURE THAT MIRRORS THE STRUCTURE OF THE GROUP

THAT IS PRODUCING IT, WHETHER OR NOT THIS WASINTENDED.

YOUR TEAM STRUCTURE WILL OVERRIDE ANY ARCHITECTUREYOU HAVE.

SOME TEAMS HAVE VERY HIGH PAIN TOLERANCE

PAIN USUALLY LEADS TO PAINKILLERS, INSTEAD OF SOLVING ACTUAL PROBLEMS

4 MISUNDERSTANDING OF FUNDAMENTALPRINCIPLESBECAUSE BLINDLY FOLLOWING PRACTICES IS NOT ENOUGH

DEPLOYMENT PIPELINE IS IN PLACE, BUT IS INCONSISTENT

DATA MIGRATIONS ARE TESTED. WITH 10 ROWS IN SQLITE

100% UNIT/API/WEB TEST COVERAGE VS. LOW MTTR / MMTD

IF SOMETHING IS DIFFICULT OR PAINFUL, DO IT MORE OFTEN (WHAT IF YOU'REDOING WRONG THING OR DOING THINGS WRONG?)

5 OPTIMIZING THE WRONG THING

PUSH

PULL INSTEAD.

Team has 32 cards in process (total WIP) anda throughput of 2 cards/day,

Average cycle time = ??? days

TAKEAWAYSOPTIMIZE THE WHOLE (IN EVERY SYSTEM, EXACTLY ONE CONSTRAINTDETERMINES THE SYSTEM’S CAPACITY)

1 COMPLETED FEATURE BEATS 10 IN PROGRESS

QAS! NEVER BE JUST TESTERS. BE TESTING FACILITATORS.

6 DELIVERING THE WRONG THING

CONTINUOUS DELIVERY IS A SOFTWARE ENGINEERINGAPPROACH IN WHICH TEAMS KEEP PRODUCING VALUABLE

SOFTWARE IN SHORT CYCLES AND ENSURE THAT THESOFTWARE CAN BE RELIABLY RELEASED AT ANY TIME

(C) WIKIPEDIA

BEFORE DOING CONTINUOUS DELIVERY, FINDOUT WHAT VALUE REALLY MEANS, FOR

WHOM AND HOW TO MINE IT.

AFTER 3 MONTHS LONG WAR, TEAM SUFFERED MANY LOSSESAND CAPITULATED. IT TOOK THEM ONE MORE MONTH TO

MOVE BACK TO GOOD, OLD AND SIMPLE STACK AND JUST 2WEEKS TO ACHIEVE THE INITIAL GOAL.
