Software functional quality
Software structural quality
5 reasons
Software quality drives predictability. Do it once and do it right, and there will be less re-work, less variation in productivity and better performance overall. Products get delivered on time, and they get built more productively. Poor quality is much more difficult to manage. Predictability decreases as re-work grows, and the likelihood of a late, lower quality product increases.
Of your team
Some companies have a reputation for building quality software. It becomes who they are, a part of their brand, and ultimately it is the expectation people have of them. Customers seek them out because of it. A good, solid reputation is hard to establish and easy to lose, but when your company has it, it’s a powerful business driver. A few mistakes and that reputation can be gone, creating major obstacles to sales, and consequently, your bottom line.
The most productive and happy employees have pride in their work. Enabling employees to build quality software will drive a much higher level of morale and productivity. On the other hand, poor products, lots of re-work, unhappy customers and difficulty making deadlines have the opposite effect, leading to expensive turnover and a less productive workforce.
A quality product satisfies the customer. A satisfied customer comes back for more and provides positive referrals. Customer loyalty is heavily driven by the quality of the software you produce and service you provide. And, let’s not forget that with the explosion of social media channels such as Twitter and Facebook, positive referrals can spread quickly. Of course that means poor quality and dissatisfaction can also be communicated quickly, if not even quicker than the good ones.
Where to start or best practices
small overview

Driver tells the car to move forward, car knows how to do it
methods should do one thing[3], once and only once (OAOO)[4], don’t repeat yourself (DRY) und single source of truth (SSOT)
Open for extensions, closed for modifications
Driver is human
Can be inherited to male or female
But not a monkey as it shares 99% of ist dna
Small interfaces
Turn left, turn right – speed and brake on different interfaces
Inject the driver by opening the door, don‘t grab the next outside
Trio
Remote
