| Vývoj software je často o hledání správné rovnováhy mezi: | |
| čistotou kódu vs. praktičností | |
| přehledností vs. flexibilitou | |
| striktními pravidly vs. pragmatickým přístupem | |
| A jak jste správně poznamenal - je to neustálý proces učení a přizpůsobování. Co fungovalo včera, nemusí být nejlepší řešení zítra. A to je v pořádku! | |
| Důležité je: | |
| Dělat informovaná rozhodnutí | |
| Nebát se změny, když je potřeba | |
| Učit se z předchozích zkušeností | |
| Zachovat si zdravý rozum a neupnout se na jeden přístup |
