Difficulty: Introductory | Prerequisites: Basic familiarity with operating systems (Windows, macOS, Linux).
Organisational needs analysis is the process a systems architect uses to audit an enterprise's current IT environment and recommend upgrades. It covers the full stack: which operating systems are in use, how many users sit on each, what server infrastructure supports them, what hardware is required, and how the network connects everything together. This is foundational material for any IT project management or systems architecture course. If you understand this, you understand the starting point of every enterprise IT overhaul.
A needs analysis inventories every layer of IT infrastructure, from OS user counts to server types to minimum hardware specs to network topology. The goal is to identify what is outdated, what is compatible, and what needs upgrading before proposing changes to stakeholders.
Organisational needs analysis
A structured audit of an organisation's IT environment, identifying current systems, gaps, and upgrade requirements. Think of it as taking stock of everything tech-related before making recommendations.
Stakeholder
Any person with decision-making authority or a vested interest in the IT project's outcome. In simple terms, these are the people who need to approve, fund, or implement the changes.
Systems architect
The IT professional responsible for designing and recommending the overall structure of an organisation's technology systems. Think of them as the person who draws the blueprint before anything gets built.
Operating system (OS)
The core software that manages hardware and provides services to applications. Windows, macOS, and Linux are the three enterprise families covered here.
Physical server
A dedicated hardware machine located on-site that hosts services, applications, or user desktops. In simple terms, it is an actual computer sitting in a server room.
Cloud-based server
A virtual server hosted by a third-party provider (e.g. Microsoft Azure, AWS) rather than on local hardware. Think of it as renting computing power over the internet instead of owning the machine.
System on a Chip (SoC)
A single integrated circuit that combines a processor, memory, and other components. It is the kind of chip found in tablets and some modern laptops.
WDDM (Windows Display Driver Model)
Microsoft's driver architecture for graphics rendering. If a graphics card supports WDDM 1.0 or later, it meets the Windows 10 display requirement.
RHEL (Red Hat Enterprise Linux)
A commercial Linux distribution designed for enterprise use, with long-term support and broad application compatibility. Think of it as the "business-grade" version of Linux.
Wired network
A network connection using physical Ethernet cables. Faster, more stable, and harder to intercept than wireless.
Wireless network (Wi-Fi)
A network connection using radio signals. More flexible and cheaper to deploy, but more vulnerable to interference and interception.
A needs analysis begins by listing every stakeholder who will influence or be affected by the project.
Typical roles include: Chief Information Officer, Systems Security Officer, Assistant Vice President of Finance, IT Project Manager, and Systems Architect.
The systems architect is usually the person conducting the analysis and drafting the proposal.
Enterprises commonly run a mixed-OS environment.
Example distribution from the case study:
Windows: 127 users (dominant platform)
macOS: 14 users
Linux: 25 users
25 users on Windows Server 2012 R2 (a legacy server OS, important to flag for upgrades)
Knowing the user count per OS drives every downstream decision: licensing costs, hardware procurement, application compatibility, and support staffing.
Physical servers are on-premises machines. In the case study: 42 physical servers.
28 running Windows 10 Enterprise
4 running RHEL
10 running macOS 10.15 Catalina
Cloud-based servers are hosted off-site. In the case study: 85 cloud servers, with a recommendation to standardise on Microsoft Azure.
The split between physical and cloud is a key architectural decision. Cloud servers offer scalability and reduced maintenance; physical servers offer direct control and can be required for compliance.
Processor: 1 GHz or faster (or SoC)
RAM: 1 GB (32-bit) or 2 GB (64-bit)
Hard disk: 16 GB (32-bit) or 20 GB (64-bit)
Graphics: DirectX 9 or later with WDDM 1.0 driver
Display: 800 x 600 resolution
These requirements are deliberately low. Even a budget machine in the $100 to $150 range will exceed them comfortably.
Requires macOS 10.9 or later as a base
15 to 20 GB of free storage
4 GB of RAM
Compatible hardware models:
MacBook (2015 or later), MacBook Air (2012+), MacBook Pro (2012+)
iMac (2012+), iMac Pro (2017+), Mac Pro (2013+), Mac mini (2012+)
The catch with macOS: the software requirements are low, but the hardware must be Apple-branded. Costs range from roughly $500 to $1,800 per machine.
Departments handling sensitive data (security, finance, executive admin) should use wired connections. Wired is faster, more stable, and harder to compromise.
Departments with lower data sensitivity (IT, HR, marketing, operations, training) can use wireless. This reduces cabling costs and increases flexibility.
The decision is driven by a risk assessment: how sensitive is the data each department handles?
Network segmentation by sensitivity level is standard practice in corporate IT. Banks, hospitals, and government agencies all wire their most sensitive departments and use wireless for general office areas. The same principle scales down to small businesses deciding which rooms get Ethernet drops.
Students often think "cloud-based" means the organisation has no physical infrastructure at all. In practice, most enterprises run a hybrid of physical and cloud servers.
Students sometimes assume macOS hardware requirements are as cheap to meet as Windows requirements. The specs are low, but Apple hardware carries a significant price premium because you cannot install macOS on non-Apple machines.
A common mistake is treating Windows Server 2012 R2 as just another version of Windows. It is a server OS with different licensing, different roles, and different upgrade paths compared to desktop Windows 10.
Students may confuse "wired is more secure" with "wireless is insecure." Wireless networks can be secured effectively; the point is that wired connections are inherently harder to intercept because physical access to the cable is required.
⚠️ Know the difference between physical and cloud-based servers, and be able to list advantages of each.
⚠️ Be able to state the minimum hardware requirements for Windows 10 and macOS Catalina from memory.
⚠️ Understand why different departments receive different network connection types (wired vs. wireless) based on data sensitivity.
⚠️ Recognise that Windows Server 2012 R2 is a legacy OS that represents a security and compatibility risk.
True or false: A cloud-based server is always cheaper than a physical server. (False, it depends on scale, usage patterns, and compliance requirements.)
Fill in the blank: The minimum RAM for a 64-bit Windows 10 installation is ______. (2 GB)
True or false: You can install macOS Catalina on any laptop that meets the RAM and storage requirements. (False, it must be a compatible Apple hardware model.)
Fill in the blank: Departments handling sensitive financial data should use a ______ network connection. (Wired)
True or false: RHEL is a free Linux distribution. (False, RHEL requires a paid subscription.)
Q: What is the primary purpose of an organisational needs analysis in IT?
A: To audit the current IT environment, from operating systems and servers to hardware and networking, and identify what is outdated or incompatible so that informed upgrade recommendations can be made.
Q: An organisation has 42 physical servers and 85 cloud-based servers. What type of infrastructure model is this?
A: A hybrid infrastructure model, combining on-premises physical servers with cloud-hosted virtual servers.
Q: Why would a systems architect recommend wired connections for the finance department but wireless for the marketing department?
A: The finance department handles sensitive financial data, making the superior security and stability of wired connections worth the additional cost. Marketing handles less sensitive data and benefits more from the flexibility and lower deployment cost of wireless.
Q: State two reasons why Windows Server 2012 R2 would be flagged for upgrade in a needs analysis.
A: It is past end-of-life support, meaning it no longer receives security patches. It also has compatibility issues with modern enterprise applications (e.g. SolarWinds does not support it).
Q: What is the key cost difference between meeting minimum hardware requirements for Windows 10 vs. macOS Catalina?
A: Windows 10 can run on almost any budget PC ($100 to $150). macOS Catalina requires Apple-branded hardware, which starts at roughly $500 and can reach $1,800, even though the software-level specs (RAM, storage) are similarly modest.
This material connects directly to IT project management, where the needs analysis feeds into project scoping, budgeting, and stakeholder communication plans. It also ties into cybersecurity fundamentals: the discussion of wired vs. wireless networks and legacy OS risks is an applied example of threat surface analysis. If the course covers cloud computing later, the physical vs. cloud server distinction here is the groundwork for that unit.
