P

STEP 01 / 07

Planning

Definition: deciding in advance what to do, how to do it, and by when, to reach a goal.

Sets the goal (identify, arrest, prove) and the order of tasks to reach it.

Ranks leads by how fast evidence decays, so the perishable ones come first.

Example: seal the store, pull CCTV and note witnesses within the first hour.

Secure the scene

Cordon, log every entry, protect evidence

Set hypotheses

Inside job? Organised gang? Rank the leads

Fix milestones

Statements in 24h, forensics in 72h, charge-sheet deadline

O

STEP 02 / 07

Organizing

Definition: arranging people and tasks into a structure with clear roles and lines of authority.

Divides the case into units, each owning one stream of evidence.

Unity of command: every officer answers to one Investigating Officer.

Example: the field unit hands CCTV clips to tech, not to three different bosses.

Scene unit

Forensics, photos, fingerprints

Field unit

Witnesses, CCTV, informants

Tech unit

Call records, digital trails

S

STEP 03 / 07

Staffing

Definition: recruiting, placing and training the right people for each role.

Matches each role to a skill set, not just to whoever is free.

Brings in outside experts when the case needs skills the station lacks.

Example: a cyber analyst traces the stolen phone’s last signal.

Specialists

Forensic experts, cyber analysts, sketch artists

Experience mix

Pair veterans with new officers

Training

Interview technique, evidence handling

D

STEP 04 / 07

Directing

Definition: guiding, motivating and supervising people so the plan gets carried out.

Turns the plan into daily orders that everyone understands.

Makes the hard calls under pressure and owns them.

Example: a morning briefing assigns each team today’s top lead.

Daily briefings

Clear orders every morning

Decide fast

Raid now or wait for more proof?

Keep morale up

Long nights, dead ends, pressure

Co

STEP 05 / 07

Coordinating

Definition: linking the work of different units so they all move toward one goal.

Keeps every unit on one shared picture of the case.

Links outside bodies: labs, banks, telecoms, prosecutors.

Example: a face from CCTV is matched against a bank’s ATM footage.

Inside

Units share leads on one case board

Outside

Forensic labs, banks, telecoms, other districts

Legal

Prosecutors check evidence will hold in court

R

STEP 06 / 07

Reporting

Definition: keeping superiors and stakeholders informed through records and reports.

Keeps seniors informed so they can step in early.

Builds the paper trail the court will test line by line.

Example: each evidence handover is signed, timed and logged.

FIR & case diary

Every step recorded, dated

Chain of custody

Who touched which evidence, when

Up the chain

Progress reports to seniors, then charge-sheet

B

STEP 07 / 07

Budgeting

Definition: planning, controlling and accounting for the money the work needs.

Estimates what the case will cost before money runs out.

Puts funds behind the leads most likely to hold up in court.

Example: fund a DNA test on the glove instead of a week of extra patrols.

Costs

Lab tests, travel, overtime, surveillance gear

Trade-offs

DNA test here or more officers there?

Accountability

Public money, audited spending
