Enterprise Architecture in a Car Park
The document outlines business requirements for developing a multifunctional car park, emphasizing the need for clarity on various intended uses such as employee, public, and police impound parking. It highlights the importance of integrating top-down and bottom-up approaches in enterprise architecture to meet capacity and accessibility requirements, while also ensuring safety, security, and revenue generation. The text also discusses architectural and solution building blocks, emphasizing their reusability and how they can be applied to define specific parking solutions.

- 8. This is muchbetter than simply ‘make a car park’ – but we still need to work with the business to develop the vision and requirement Capacity Requirements - Accessible parking? - Motorbikes? - Definition of Vans? & Cars? Top Down – work with the business to find out what they need Bottom Up – look at the technical design and feed back what can be achieved EA is meant to be done Top Down but can support a Bottom Up approach - Approved standards base - Reusable architectural blocks - Reusable solutions blocks Project Mandate / Architecture Vision Design a public pay-to-use car park which will support the business case requiring 200 car parking spaces & 10 van parking spaces
- 9. Intuitive - Easy tonavigate and use for new or infrequent users - Clearly provide all necessary information to effectively use - Comply with all legal requirements for layout and signage - Lighting to see / use the information & navigation signage Safe & Secure - Cameras, lighting - Road traffic and pedestrian interaction - Regular patrols - Service inspection (roadway, markings, signage) Revenue Generating - Parking ticket purchase on-site (TVMs – cash, card, phone – short term) - Parking ticket pre-purchase (online – long term) - Maintenance / repair / redundancy of TVM services - Cash collection from TVMs - Revenue collection and accounting (web, phone, card, cash) - Revenue enforcement - Inspections, clamping, vehicle removals, punitive damages Sample Requirements
- 10. Architectural Building Blocks …areabstract definitions of ‘things’ Helps to identify and define common blueprint components which may be reusable A ‘car’ architectural building block: A rectangular, self propelling carriage on 4 wheels navigated by a human driver A ‘parking space’ architectural building block: An accessible demarcation within which a vehicle can comfortably fit with sufficient space for the occupants to disembark from the vehicle The ‘car’ architectural building block and then be applied to the ‘parking space’ building block to make a ‘car parking space’ architectural building block Similarly other vehicles can make other parking space building block variations, such as the Van parking space requirement
- 11. Solution Building Blocks …aremore specific definitions of ‘things’ A solution building block - makes the abstract architectural building block concrete or real - fulfils requirements - is reusable or replaceable - is product or solution aware A ‘car’ solution building block Maximum dimensions (LxW) = 3.8m x 1.8m; maximum weight 2t Is driver controlled and the driver has visibility through front and side facing windows Self-propelled; capable of speed control, reversing & complete stop; has perma-brake A ‘car parking space’ solution building block 2m x 4m flat surface with incline <= 1:1.05 and direct access on one narrow edge A solution can then be sought based on the solution building block definitions: Car: Honda S2000, VW Golf, Ford Transit? Car Parking Space: painted lines on road surface, tray in parking cylinder
- 12. Realised Reusable Solutions Acommon definition of a car means we can make a common car parking space - This leads to layout options - Which informs capacity
- 13. Extensible Solutions Building blockscan be used as components of other building blocks - In this case 2 car park spaces have been used to make a cabin - 3 spaces can be used to make a van stop - 3 normal spaces can be used to create 2 more accessible spaces - 1 normal space can make 2 motor bike parking spaces

Let’s try: Pedestrianroad crossing Requirement: Facility for pedestrians to cross the road Derive various Solution Building Blocks • How busy the road is • What warning / visibility is required? – Young children @ school crossing (lights, signs) • Can traffic be stopped? If so other SBBs apply • Adhere to country-specific road law
