Ha rendszeresen jönnek üzleti igények, amelyeket az üzlet minél hamarabb éles üzembe szeretne látni, hogy pénzt tudjon keresni, akkor a gyors megoldások mentén beszivárognak rossz megoldások is. Ezeket a tákolásokat előbb-utóbb kell oldani, mivel hibákat rejtenek magukban a le nem kezelt használati esetekre, illetve a fejlesztők képesek precedens értékűnek tekinteni ezeket a megoldásokat és egyszerűen lemásolják, mint gyors megoldás.</p> <p style="margin: 10px 0 0 0">A forráskód teremtette adósság növekedésnek másik ága az, hogy a világ is változik a meglévő forráskód körül, ami jó megoldás volt pár hónapja vagy éve, az mára már elavult. A használt keretrendszerek is változtak, esetleg új keretrendszerek jöttek ki, amelyekkel megoldhatóak az eddigi kerülő megoldások... <img class="emoticon emoticon-smile" src="http://wiki.javaforum.hu/s/en_GB-1988229788/4727/ffd10e10ff7bc0a1d7e29b4d2225707dd7f03d0b.13/_/images/icons/emoticons/smile.png" data-emoticon-name="smile" alt="(smile)" style="vertical-align: middle" /></p> <p style="margin: 10px 0 0 0"> <img class="confluence-embedded-image confluence-external-resource image-center" width="500" src="https://lh4.googleusercontent.com/mN9Z1YRz4dSJTIShJldLpPE84hvG69AxxjS6dM3ypsyXv8Da8628rBDNs52EXKGYowTVnwvOhD-tBfijAfRgI0X00pGkezVNbYVEZev8pfkCo20PpOwI-t2oIA" data-image-src="https://lh4.googleusercontent.com/mN9Z1YRz4dSJTIShJldLpPE84hvG69AxxjS6dM3ypsyXv8Da8628rBDNs52EXKGYowTVnwvOhD-tBfijAfRgI0X00pGkezVNbYVEZev8pfkCo20PpOwI-t2oIA" /></p>

A nagy különbség pedig az, hogy ha nem nyúlunk a forráskódhoz, akkor a kompetencia adósság jobban növekszik, mint a technikai, amely általában akkor növekszik, ha üzleti nyomásra módosítjuk a kódot és nem állunk meg rendet tenni.</p> <p style="margin: 10px 0 0 0">Nálatok mekkora a <em>Competence Debt</em>? <img class="emoticon emoticon-smile" src="http://wiki.javaforum.hu/s/en_GB-1988229788/4727/ffd10e10ff7bc0a1d7e29b4d2225707dd7f03d0b.13/_/images/icons/emoticons/smile.png" data-emoticon-name="smile" alt="(smile)" style="vertical-align: middle" /></p> </td>
