Network Management


Assignment-3 marking guidelines
The following are the major assessment criteria of this assignment
Task 1: Investigate and report the current network status
In this task, your team will be assessed based on
• The information about the network you have collected through the site survey. The more details about the network your team can obtain the higher marks you will get. At the minimum, your team should obtain the following key information:
o The estimated number of network users
o High-level logical topology of the network
o IP addressing scheme
o Key applications and services
o Performance baselines for accessing key applications and services
o Wi-Fi channels and overall area of coverage
• The method, technique and tools your team uses to collect the information. Discuss briefly about how each piece of information is collected.
Task 2: Propose upgrade solutions
In this task, your team will be assessed based on
• The correctness, feasibility and future-proof of the proposed solutions. A good solution should be technically correct, feasible in terms of budget, taking into account the future network growth and using the current network technology.
• The technical details of the solutions. Each solution should be provided with a sufficient level of technical details so that its working mechanism can be understood and the cost to implement the solution can be estimated. At the minimum, you will need to provide the high-level logical and physical design of the solutions with the list of major hardware and software to be obtained.
• The analysis to select one solution. Your team can perform cost-benefit analysis to select one solution over the two proposed. Discuss how the selected solution would expect to solve the identified problem and how does this align with the university long-term business goal and strategy as stated in the university annual reports.
Task 3: Present and defend the proposal
In this task, your team will be assessed based on
• The presentation structure and quality. A good presentation will have a clear structure showing the scope of the presentation. The slides present only the key points. Text and images are clearly presented.
• Presenter performance. Present clearly and engage with the audience. Finish the presentation on time. Handle questions with confidence and quality answers.
Peer assessment
Each team member will assess other member contribution and performance using the 100% scale. For example, if the team has 2 members, a possible scale can be 50% and 50%. The individual mark will be scaled taking into account the peer assessment.

Current Situation
Strategic Alignment
This section sets out the problem that the Proposal is responding to, or the opportunity. Also, use graphs, reference material, images to tell the story of the current situation.
State the university business objective that options for this network upgrade proposal.
Explain briefly how the investment on the network upgrade could assist the university to deliver its outputs and outcomes more effectively and efficiently.
Current Technical Environment
Describe the current situation not only from a business perspective – but also from a current technical perspective. The Technical Environment section should document relevant components of your current ICT baseline. The section should describe:
• The estimated number of network users
• High-level logical topology of the network
• IP addressing scheme
• Key applications and services
• Performance baselines for accessing key applications and services
• Wi-Fi channels and overall area of coverage
Business Problem
State all reasons for the network upgrade proposal. For example, how the upgrade could
• Support stakeholder priorities and business needs
• Enhance the level of service delivered to stakeholders
• Reduceoperation costs and increase incomes
• Overcoming the limitation and constraints of a current solution
Stakeholder Impact
Describe the impact of the current situation on stakeholders
Current Risks
Describe the risks that the current situation creates, and the risks of not responding to the current situation. Include both business and technical risks.
Proposed Response
Having identified the “Why” of the business case, the Proposed Response starts to articulate the “What” is being proposed to be done in response.
This is about identifying the desired end state or destination, rather than the detail of “How” to get there.Include a description of the proposed response, including any evidence that this will be an effective response to the current situation. This section should focus on ‘what’ is being proposed as a response, rather than ‘how’ that response can be delivered.
Strategic Alignment
Identify how the proposed response aligns with the university strategic objectives listed in the current situation section. Use the result from your cost/benefit analysis to identify the outcomes that delivery of this response would support.
Technical Environment
Describe the future state of the technical environment based on the proposed response (not the specific options). High level environment and architecture diagrams can be helpful, but keep in mind the audience for the document when thinking about the degree of technical detail to include.
Business Environment
Describe the future state of the business operational environment based on the proposed response.
Benefits
Provide a statement of the benefits that the project will achieve and indicative timing for when they will be realised. Include information on how benefits will be measured and the expected targets to be achieved for each measure.
Include interim and longer term benefits and include any identified disadvantages.
Proposal Summary
The information provided about the current situation, the proposed intervention and the expected benefits may usefully be summarised in a high level visual representation.
Solution Options
Design Criteria
Include where possible the high level requirements that any viable solution will be expected to deliver against. Note high-level business requirements that the design must address – for example, consider criteria such as:
• Functionality
• Performance
• Reliability, availability and maintainability
• Usability, flexibility, scalability, interoperability
• Security and privacy
• Cost
These requirements provide the criteria for comparing options. Indications of relative value will be informative.
Identified Options
The business case must consider a range of options ranging from minimal technology upgrades to more innovative solutions. This ensures that all options are considered objectively on their merits. The outcome will be a shortlist of options for analysis and comparison in the cost-benefit analysis.
So in this section, briefly describe about the upgrade options (2 options as the minimum) from the technical and technological perspectives.
Options Analysis
Summarise the most significant features of each option. A preliminary analysis of the Net Present Value (NPV) of the proposal should be included. The NPV analysis should summarise the value flows associated with key costs and benefits, discounted to a present value using an appropriate discount rate. Present a tabular comparison of the options against costs, design requirements listed above and risk.
You may consider to use a tabular format option as shown below:
Requirements Option 1 Option 2
Benefits
Total Costs (Over n Years)
NPV: $XXm
Requirement 1
Requirement 2
Requirement 3
Any Risk
Conclusion (e.g.) 2nd Ranking Option Preferred Option

Option Details
Repeat this section for each option, including the following sub-sections:
• Description: provide a description of the option
• Stakeholder Impact: Provide an assessment of the stakeholder impact, both positive and negative should this option be implemented.
• Cost: ICT-related costs are expense and capital costs, including infrastructure, software, administration, maintenance and resourcing costs.
• Benefit
• Cost-Benefit Analysis: This assessment is based on the net present value (NPV) method where appropriate.
• Risk: Provide a high-level risk assessment that identifies the main risks
• Schedule: Provide a broad schedule linking the major cost elements, and showing the significant milestones affecting or constraining any schedule.
Implementation Approach
Describe the implementation approach for delivering the investment, including the project/programme management governance structures and other key control and assurance processes, describing variations for each identified option if different.
Supporting Materials
Provide any additional material that supports the business case. The material may include
• Detailed cost/benefit analysis of each solution
• Analyses on related technical/technological solutions found in the literature
• Commitment/support from the solution and technology providers
• Interview with key people in the organisation about the proposed solution
• Etc.
