A Network Management System (NMS) can be often divided into five functional areas, commonly referred to by the FCAPS model, which stands for:

1. Fault Management: This involves detecting, isolating, diagnosing, and correcting network problems to keep the network running effectively. It includes monitoring and notifying the network administrator of issues like link failures, malfunctioning devices, or other problematic issues that might affect the network’s performance.

2. Configuration Management: This area deals with the setup of network devices and software to operate with optimal performance and security settings. It includes tasks like configuring new devices, modifying settings on existing devices, tracking configuration changes, and ensuring that the settings applied are within the policies defined for the network.

3. Accounting Management (sometimes referred to as Administration Management): This focuses on tracking and billing for the use of network resources. It can involve measuring resource utilization by users, departments, or specific applications, and possibly implementing chargeback mechanisms to allocate network operation costs to those entities that generate the most traffic or require special resources.

4. Performance Management: This involves monitoring and measuring network performance on a continuous basis to ensure that network performance remains at acceptable levels. It includes the collection of data to evaluate parameters such as network throughput, latency, packet loss, and availability. Performance management helps in identifying trends that may indicate future problems and offers opportunities to optimize resources.

5. Security Management: This focuses on protecting the network and its resources from unauthorized access,

Performance management is a strategic approach to creating and sustaining improved performance in employees, thereby delivering better results for an organization. It’s about aligning the organization’s objectives with employees’ agreed measures, skills, competency requirements, development plans, and the delivery of results. The emphasis on performance management is on improving the future effectiveness of employees and, ultimately, the organization. This involves ensuring that employees understand the importance of their contributions to the organizational goals, providing feedback on their performance, offering training to develop their skills, and rewarding accomplishments appropriately.

Performance management is closely related to several key activities in the human resources and management fields:

1. Goal Setting: It involves setting clear and specific performance goals for employees that are aligned with the company’s strategic objectives.

2. Continuous Feedback: Regular, constructive feedback helps employees understand how well they are performing and what improvements are needed.

3. Performance Appraisals: These are formal assessments where an employee’s performance is documented and reviewed, usually annually or semi-annually.

4. Training and Development: Identifying areas where employees can improve their skills or acquire new ones to better perform their roles.

5. Reward and Recognition: Acknowledging and rewarding employees’ efforts and contributions towards achieving organizational goals.

6. Career Planning: Assisting employees in planning their career paths within the organization to achieve personal goals that align with organizational objectives.

Through these interconnected activities, performance management aims to cultivate a high-performance culture where continuous improvement and excellence are encouraged and
