| Organization Size | Number of employees, users, devices, departments, and locations requiring network access. | Small office: up to 100 users Growing organization: 101–500 users Larger organization: more than 500 users | Scalable switching, centralized policy control, modular expansion, and simple onboarding. | Maximum supported users, available ports, uplink capacity, and expected three-year growth. | High |
| Number of Sites | Headquarters, branches, warehouses, remote offices, and temporary locations. | Single site, 2–10 sites, or more than 10 sites. | Consistent configuration, centralized monitoring, secure site connectivity, and remote troubleshooting. | Deployment time per site, configuration consistency, and availability of centralized management. | High |
| User and Device Density | Computers, phones, cameras, printers, sensors, servers, and guest devices connected simultaneously. | Low density: fewer than 10 devices per user High density: 10 or more devices per user | Sufficient access ports, Power over Ethernet, device profiling, segmentation, and capacity for peak usage. | Port utilization, wireless client capacity, PoE budget, and peak concurrent connections. | High |
| Application Traffic | Business-critical applications such as voice, video meetings, cloud software, file services, and backup systems. | Low bandwidth: below 1 Gbps per access segment Higher demand: 1–10 Gbps or more per aggregation segment | Quality of service, traffic prioritization, low latency, resilient uplinks, and adequate switching capacity. | Latency, packet loss, jitter, throughput, and utilization during the busiest business period. | High |
| Internet and WAN Connectivity | Internet service capacity, backup circuits, cloud connectivity, remote users, and inter-site traffic requirements. | Common business links range from 100 Mbps to 10 Gbps, depending on site size and workload. | Redundant links, automatic failover, traffic steering, secure tunnels, and application-aware routing. | Failover time, link utilization, uptime target, and performance of critical cloud applications. | High |
| Security and Segmentation | Required separation for employees, guests, voice, cameras, operational systems, and sensitive data. | At least 3–5 logical segments for many small and medium environments; more may be required for regulated operations. | Access control, network segmentation, identity-based policies, secure remote access, threat detection, and logging. | Policy coverage, authentication success rate, incident response time, and audit-log retention. | High |
| Wireless Access | Office layout, user density, roaming requirements, guest access, voice over wireless, and high-bandwidth applications. | Basic offices may need one access point per 1,500–2,500 square feet; dense spaces generally require more detailed radio planning. | Modern wireless standards, automatic radio optimization, secure guest access, seamless roaming, and centralized visibility. | Signal strength, channel utilization, client throughput, roaming performance, and coverage in critical areas. | High |
| Availability and Resilience | Business impact of network downtime and the systems that must remain operational during equipment or link failure. | Standard operations may target 99.9% availability; mission-critical environments often require higher targets. | Redundant power, link aggregation, gateway redundancy, backup connectivity, and maintenance without major disruption. | Recovery time objective, recovery point objective, failover duration, and single points of failure. | High |
| Management and Operations | IT team size, technical expertise, monitoring requirements, change frequency, and preferred deployment model. | Small IT teams generally benefit from automation and centralized management; larger teams may require granular administrative control. | Unified visibility, zero-touch deployment, configuration templates, alerts, analytics, and role-based administration. | Mean time to detect, mean time to resolve, number of manual steps, and configuration drift. | High |
| Compliance and Data Protection | Industry regulations, sensitive information, retention requirements, audit obligations, and geographic restrictions. | Requirements vary by industry and jurisdiction; document applicable controls before selecting equipment. | Encryption, access logs, secure administration, policy enforcement, software maintenance, and reporting. | Audit readiness, log completeness, encryption coverage, privileged-access reviews, and patch compliance. | Medium |
| Growth and Lifecycle | Expected user growth, new offices, additional devices, application expansion, and replacement timeframe. | Plan for at least 20–30% spare capacity over the current requirement where practical. | Expandable port density, higher-speed uplinks, software feature continuity, and predictable upgrade paths. | Remaining port capacity, available bandwidth headroom, support lifecycle, and upgrade cost. | Medium |
| Budget and Total Cost | Hardware, licensing, support, installation, training, power, maintenance, and future expansion costs. | Compare total cost over three to five years rather than evaluating purchase price alone. | Transparent licensing, energy efficiency, reusable infrastructure, automation, and predictable support costs. | Three-year or five-year total cost, operating cost per site, and cost per connected user. | Medium |
| Selection Decision | Rank requirements by business impact, technical necessity, implementation risk, and future relevance. | Use a weighted scorecard; assign higher weight to security, availability, performance, and operational simplicity. | Requirements traceability, proof-of-concept testing, documented acceptance criteria, and a phased rollout plan. | Weighted score, test results, risk register, deployment milestones, and stakeholder approval. | High |
