Question

Accepted Answer

**Build versus buy** takon apa-apa arep dikembangake ana ngomah utawa nggumakake produk utawa layanan sing wis ana. Kadhafaran kanggo bangun kuwi kuat lan asring salah, biaya nyata saka bangun kalebu taun-taun perawatan, ora mung versi pisanan. Kaputusan iki gumantung apa iki *inti* kanggo bisnis mu.

LEAN BUY when:                     LEAN BUILD when:
- It's NOT your core differentiator  - It IS your core value/differentiator
- A mature solution exists           - No good solution fits your needs
- Speed-to-market matters            - You need deep control/customization
- You lack expertise to maintain it  - Long-term cost of buying is prohibitive
- TCO of buying < building+upkeep     - Vendor lock-in is an unacceptable risk

## Conto konkrit

Jangan bangun sistem autentikasi dhewe-dhewe, identitas iku rumit, kritikal keamanan, lan ora dadi pembeda mu; tuku/integrasikake penyedia sing wis teruji. *Bangun* mesin rekomendasi inti mu yen rekomendasi iku sing nggawake produk mu istimewa. Bangun apa sing nggawake *sliramu*; tuku sing liyane.

## Itungan biaya sejatine

Tim asring nyumbang ngukur bangun: versi pisanan iku 20% saka biaya umur. Perawatan, patch keamanan, kasus pinggir, lan on-call ngluwihi iku. Itungan total biaya ownership saletanan taun, ora demo sing bisa dikirim ing sprint.

## Jebakan

"Ora dikumpokarake ana kene" nyebabake ngbangun maneh masalah sing wis kelar; tuku butho nyebabake vendor lock-in lan piranti sing ora pas. Mutus kanthi sungguh-sungguh, saben kasus.

## Alasan iki penting

Bangun bab sing salah ana ngomah ngubur taun-taun tenaga engineering kanggo kerja sing ora beda.

Dapat iki bener konsentrasi waktu engineering sing sithik mu ing apa sing sejatine nggawake bisnis menang.
