Unajifanya namna, kupanga, na kulipa kwa nini jengo la kiufundi?

Question

Accepted Answer

**Technical debt** ni pengo kati ya jinsi kanuni iko na jinsi inapaswa kuwa, iliyochukuliwa (kwa kasd au la) ili kuhamia haraka zaidi. Baadhi ya wajibu ni nzuri; kazi ni kuisimamia, sio kuiondoa. Susi ni kupanga chanzo ambacho kwa kweli *kina madhara*.

## Sipa kulingana na athari, si usumbufu

```text
For each piece of debt, ask:
  - How often does it slow us down or cause bugs? (frequency)
  - How bad is it when it bites? (severity)
  - How risky/expensive is it to fix? (cost)

High frequency + high severity + low cost → fix now
Low frequency + low severity → leave it, document it
```

## Mfano halisi

Moduli nyinyi ambayo huvunjika kila kutolewa na kuweka timu kila wiki ina thamani ya kuweka. Adat ambayo haipo lakini imara ambayo hakuna anayogusa ni *si*, hata kama inakulaani. Kujenga upya ni vanity, sio thamani.

## Jinsi ya kumfadhili kazi

Spriniti safi za "deni" hazijakubali. Mkakati wa vizuri:

```text
✓ Budget ~10-20% of each sprint for debt continuously
✓ Pay debt down inside related feature work ("boy scout rule")
✓ Tie debt to business pain: "this is why feature X took 3 weeks"
```

## Kwa nini kinamaanisha kitu

Deni ambalo haulijengwa linakusanya: kasi inyonyesha hapo mahali timu haiwezi kusambaza kitu.

Lakini kufanya kazi kila dosari kubwa hubazezu wakati kwa deni ambalo halijali.

Thamani ya TL ni kujua tofauti na kufanya kesi kwa viongozi katika majibu ya *biashara*, sio tu engineering.
