The focus means NOT doing things
#2
z
Focus
• Atlassian does not negotiate prices, does not do customisations, does not implement their products on a customer site.
• IKEA does not manufacture custom stuff, does not offer transport, does not provide assembly service (just via partner companies)
• Twitter does not support tweets longer than 140 characters*

Time - the most limited and valuable resource
• Founders’ time is super precious - treat it as it would cost 1000 USD per hour. Then think if it’s worth spending on what you spend it.
• Everything you do, own, think about or care for introduces a tax. This tax sooner or later will kill you, unless you start limiting what you do, own, think about or care for.

(De)Focus - our case• Services for Atlassian - interesting for engineers & quite profitable,
limited short and mid-term risk, no diversification • Consulting & custom development - very exciting, access to field
market, source of ideas and real requirements, good money, not scalable, could be risky and tiresome (e.g. migrations scheduled for Easter)
• Training services - great money vs time spent, not scalable, no risk • Own products - risky, potential highest ROI, most emotionally rewarding,
scalable.

Automation introduced too early is a waste
#4

Our story - waste at Spartez
z
Problems with automation
• Once automation is introduced it removes us from better understanding of given process (unless we keep paying close attention to it). If it’s too early…
• Automating of a bad process does not make it any good.
• Usually given process won’t survive the initial contact with the battlefield, automating it too early is then a pure waste.
“There is nothing quite so useless, as doing with great efficiency, something that should not be done at all.”, Peter Drucker

Too much order means seeking your comfort zone

Engineers seek Order
• By default engineers want to see or establish an Order around them
• Software engineers want it even more, as the software is infinitely flexible - refactoring, renaming, code style, process improvement & automation
• This is all good, but … it’s also seeking your comfort zone - something where everything is under your control, everything is predictable, everything is safe Photo by Rich Renomeron - CC BY-NC-ND 2.0

The beginning vs the end in practice• brownfield projects • deployment • documentation • effective & timely support • bug-fixing • security fixes • performance improvements • handling incidents • roll-backs and roll-forwards • migrations, upgrades • user training & onboarding
• greenfield project • proof of concept • evaluation of new technologies • initial design • planning • “inception” (a la RUP) • prototyping • alpha versions • rewriting • redesigning • rearchitecting
While there is value in the items on the left, users & customers value the items on the right more.

The most important skill for engineersis communication
#7
z
Software Engineering is about Humans
• Engineering is about working with humans for humans (solving their problems) • We are taught so little about how to work with humans - how to communicate • Software development nowadays is a team sport

Half-products are worth far less than half.
#8
z
“Sure, it’s possible”
• Developers have tendency to treat half-baked products as “done”. • Half-baked means: those which still require installation, customisation, reading
documentation (because they are unintuitive), configuration or even scripting/programming. • “Sure, it’s possible” - is the mantra we love to use, but our customers hate. • A lot is “possible”. It’s even possible that you will be Polish president one day. • “Possible” does not mean anything in software. It has to work here and now - ideally OOB,
intuitively, fast.
A product almost solving customer problem cost only a small fraction (if you are lucky) of what it could cost if it was solving entirely the customer problem.

Matching founders are key#9

Matching = As different as possible with similar values and passions
Matching ≠ Identical
z
(Theoretical?) Example1. super strong technically, challenging everything and everyone, perfectionist, pessimist 2. bringing order & peace, totally reliable and responsible, predictable, realist 3. super fast builder & learner, caring for customers, mission-impossible person, optimist 4. influencer, inspiring, having strong vision, idealist

Small and simple is easyBig and simple is damn difficult
#10
z
Dealing with complexity is hard• The simplicity needs constant care (our energy), complexity increases autonomously
otherwise. • One cannot achieve simplicity by adding things to already complex (or complicated)
system. Simplicity is achieved by removing, not adding. • When your organisation grows you are adding things. It’s very difficult to remove
anything. People think that adding is great and removing is bad. I am yet to see how to overcome it.
• Some simple development rules apply nicely: avoid ifs (corner cases), DRY (duplicate functions), name functions well and … refactor.
• It’s easy to kill diversity and innovation by the attempts to achieve simplicity by standardisation. <=>

#11

So, do we software engineers suck as CEOs?
• understand technology - the best currently vehicle letting us change the world • share knowledge, intensely collaborate (feel secure) • have attention to details, are precise in setting and measuring goals (e.g. growth hacking) • strive for simplicity • are used to work with quick cycles with a short feedback loop - key to learn fast • can fail fast • inspire masses - bringing innovations from IT to all other industries
It’s not that bad after all. We have a huge potential!
