Kepiye cara ngira-ira kerja lan ngatur jadwal?

Question

Accepted Answer

**Perkiraan** yaiku pamacan sabarning wektu sing kabutuhake; **manajemen jadwal** yaiku ngrancang lan nyesuaieke mriksa pamacan kasebut. Kasunyatan pokok: perkiraan iku *tebakan probabilistis*, dudu janji — lan ngerlakoni perkiraan minangka janji kuwi dadi asal-asale pirang-pirang masalah jadwal.

## Teknik perkiraan

```text
✓ BREAK DOWN → estimate small tasks; big things are always underestimated
✓ RELATIVE sizing → story points / t-shirt sizes (S/M/L) over false-precise hours
✓ Use HISTORY → what did similar work actually take? (velocity)
✓ THREE-POINT → best / likely / worst case to capture uncertainty
✓ Involve the people DOING the work — not just the lead
```

## Pertimbangake ketidakpastian lan kenyataan

```text
✓ Add buffer for the unknown (integration, review, bugs)
✓ Remember NON-coding time → meetings, support, code review, testing
✓ Beware the planning fallacy → people are reliably optimistic
✓ Express ranges, not single points → "3–5 days," not "4 days"
```

## Ngatur jadwal

```text
✓ Track progress vs. plan continuously
✓ Surface slippage EARLY — bad news doesn't improve with age
✓ Re-estimate as you learn; the plan is a hypothesis
✓ When behind, adjust scope/resources/date — don't just hope
```

## Conto konkreto

Ditakoni "sabarning wektu kanggo dashboard anyar?", jawaban lemah yaiku "rong minggu." Jawaban kuwat: pecah dadi tugas, ukurake saben tugas, tambah buffer, lan ngomong "bisa dadi 2–3 minggu, karo bagean ekspor data minangka resiko paling gedhe." Kuwi ngandharake kanthi tulus lan nerangake pangerte-ningale slip.

## Kesalahan umum

Menehi tanggal tunggal sing dijamin ing ngisor tekanan, banjur ditandhangi. Utawa ngisi nglir-nglir — luwih apik transparan bab ketidakpastian lan risiko.

## Apa gunane

Jadwal sing ora realistis nyebabake crunch, nyorot sudhut, lan kapercayan rusak.

Perkiraan kanthi tulus lan adhedhasar jangkauan nyeting pangarepan kanthi bener lan tahan kontak karo kenyataan.

Perkiraan kuwi pamacan, dudu kontrak.

Keterampilan iku andharake ketidakpastian kanthi cetha lan nyesuaieke cepet nalika kenyataan beda karo rencana.
