3. Current system or situation

3.1 Background, objectives and scope

[History of the current operation, what it is meant to achieve, and the area it covers.]

3.2 Operational policies and constraints

[Rules and limits that govern current operations: staffing levels, shift patterns, response targets, legal duties, budgets.]

3.3 Description of the current system or situation

[How work is done today: the tools, the steps, the information flows and the hand-offs. Include manual steps and spreadsheets; they are part of the real system.]

The current flow is shown below.

3.4 Modes of operation

Mode	Description
Example: Normal	Two call takers and one dispatcher per county
Example: Surge	Off-duty staff recalled by phone tree; average 40 min to staff up
Example: Backup site	Paper-only operation from the fire station annex
[Mode]	[Description]

3.5 User classes and other involved personnel

User class	Number	Responsibilities	Skills and training	Interaction with system
Example: Call taker	36	Answer calls, record details	6 weeks certification	Telephone, paper cards
Example: Dispatcher	18	Assign units, track status	3 years experience typical	Radio, whiteboard
Example: Field unit crew	420	Respond to incidents	Varies by service	Radio
[Class]	[n]	[Responsibilities]	[Skills]	[Interaction]

3.6 Support environment

[Who maintains today's equipment and procedures, support hours, spares, and known support problems.]

4. Justification for and nature of changes

4.1 Justification for changes

[Problems, deficiencies and new needs that justify change: missed targets, growth, new regulation, obsolete equipment. Quantify them.]

Example: In the last 12 months, 22% of priority calls missed the 8-minute response target. Post-incident reviews attribute 60% of those misses to dispatchers not knowing the nearest available unit.

4.2 Description of desired changes

ID	Desired change	Type	Problem addressed
CH-01	Example: Show live unit locations to dispatchers	Capability	Nearest unit unknown
CH-02	Example: Share incidents across county boundaries	Interface	Border incidents delayed
CH-03	Example: Electronic call records	Data	Lost or illegible cards
CH-04	[Change]	[Capability / Interface / Personnel / Environment / Support]	[Problem]

4.3 Priorities among changes

Priority	Changes	Reason
Essential	CH-01, CH-03	Directly affect response time and legal record keeping
Desirable	CH-02	Benefit limited to border areas
Optional	[CH-nn]	[Reason]

4.4 Changes considered but not included

[Changes discussed and rejected or deferred, with the reason, so they are not raised again without new information.]

Example: Automatic unit assignment without dispatcher confirmation was rejected because the services' unions and medical directors require a human decision for every dispatch.

4.5 Assumptions and constraints

[Assumptions and constraints that apply to the proposed changes: funding, existing radio network, staff numbers, legal limits.]

5. Concepts for the proposed system

5.1 Background, objectives and scope

[What the proposed system will achieve and the operational area it covers.]

5.2 Operational policies and constraints

[Policies that will apply in the future operation, including new ones created by the system.]

5.3 Description of the proposed system

[How the operation will work: main components as users see them, the information each user has, and the flow of work.]

The proposed flow is shown below.

5.4 Modes of operation

Mode	Description	Change from today
Example: Normal	Each county staffed as today; shared incident view	Common picture across counties
Example: Surge	Any console can take any county's calls	Staffing shifts in minutes, not 40 min
Example: Degraded	Local cache keeps incidents if the data centre link fails	Paper fallback only as last resort
[Mode]	[Description]	[Change]

5.5 User classes and other involved personnel

User class	Future responsibilities	New skills needed	Training
Example: Call taker	Records incidents directly on screen	Structured questioning in the platform	2 days
Example: Dispatcher	Confirms suggested assignments	Map-based dispatch	3 days plus simulator
Example: Field unit crew	Acknowledges incidents on terminal	Terminal use	2 hours
[Class]	[Responsibilities]	[Skills]	[Training]

5.6 Support environment

[Future support: service desk, hours, vendor support, spares for vehicle terminals, maintenance windows.]

6. Operational scenarios

6.1 Scenario OS-01: [Normal operation, for example Single priority call]

Situation. [Who, where, when, and the starting state.]

Example: Weekday afternoon, normal staffing. A caller reports a person collapsed in a supermarket.

Step	Actor	Action	System response
1	Caller	Dials emergency number	Call routed to free call taker; caller location shown
2	Call taker	Records location and complaint	Incident created, priority 1 suggested
3	Dispatcher	Reviews three suggested ambulances	Travel times shown for each
4	Dispatcher	Confirms nearest unit	Incident sent to vehicle terminal
5	Ambulance crew	Acknowledges, drives to scene	Status "en route" with live position
6	Ambulance crew	Marks "on scene"	Response time recorded automatically

Outcome. Unit on scene in [n] minutes; complete electronic record. Demonstrates. CH-01, CH-03.

6.2 Scenario OS-02: [Peak or stress, for example Multi-vehicle collision on county border]

Situation. [Starting state.]

Step	Actor	Action	System response
1	Several callers	Report the same collision	Platform flags possible duplicates by location and time
2	Call taker	Links calls to one incident	Single incident with all caller details
3	Dispatcher (county A)	Requests units from county B	Units from both counties shown on one map
4	Dispatcher (county B)	Approves loan of two units	Units assigned; both dispatchers see status
5	Incident commander	Requests more resources	Request logged; supervisor alerted

Outcome. [Result.] Demonstrates. CH-02.

6.3 Scenario OS-03: [Failure, for example Loss of data centre link]

Situation. [Starting state and the failure.]

Step	Actor	Action	System response
1	Platform	Detects loss of link	Consoles switch to local mode and show a banner
2	Call taker	Continues recording incidents	Incidents stored locally
3	Dispatcher	Assigns units by radio	Assignments recorded locally
4	Platform	Link restored	Local records synchronised; conflicts listed for review
5	Supervisor	Reviews conflict list	Record corrected and signed off

Outcome. [Result.] Demonstrates. [Mode or requirement.]

6.4 Scenario OS-04: [Maintenance or support, for example Vehicle terminal replacement]

Situation. [Starting state.]

Example: A vehicle terminal in an ambulance fails at the start of a night shift. The ambulance is otherwise ready for service.

Step	Actor	Action	System response
1	Ambulance crew	Reports terminal fault to the service desk	Ticket opened; unit flagged "radio only" on dispatcher map
2	Dispatcher	Continues to assign the unit by radio	Assignments entered on the crew's behalf and logged
3	Fleet technician	Swaps terminal from spares stock	New terminal registers itself to the vehicle
4	Platform	Pushes current incident and settings to the terminal	"Radio only" flag cleared
5	Service desk	Closes ticket with time to repair	Repair time recorded for support reporting

Outcome. The unit stays in service throughout; no incident data is lost. Demonstrates. Support environment in 5.6, CH-01.

7. Summary of impacts

7.1 Operational impacts
