Q1. Time Series Forecasting Methods Comparison

Time Series Components

• Trend (T)
• Seasonality (S)
• Cyclical (C)
• Random (R)

Forecasting Methods

Naïve Method

Formula: Ft+1 = At

• Assumes next demand equals last demand.
• Used as a benchmark.

Simple Moving Average (n)

Formula: Ft+1 = (At + At-1 + … + At-n+1) / n

• Smooths random variation.
• A higher 'n' increases lag.

Weighted Moving Average

Formula: Ft+1 = w1At + w2At-1 + … + wnAt-n+1

• Sum of weights (Σw) equals 1.
• Recent data is given a higher weight.

Exponential Smoothing

Formula: Ft+1 = αAt + (1−α)Ft

• Where 0 < α < 1.
• A higher α increases responsiveness.
• Most widely used method.

Comparison Summary

The Naïve method is the simplest. The Moving Average (MA) smooths noise. The Weighted Moving Average (WMA) is more...

Media and Technology Glossary

Journalism and Broadcasting

• Stringer: A freelance journalist.
• Shortlist: A list chosen from a longer list.
• Scoop: A story that one broadcaster (or newspaper, etc.) manages to get as an exclusive. This can often lead to a sharp rise in audience figures, as there is only one source of this information.

• Ensuring accountability
• Enhancing learning for future projects

Objectives of Project Evaluation

• To assess whether the project has met its intended goals and objectives
• To evaluate the efficiency and effectiveness of project execution
• To support decision-making for similar future initiatives

Principles of Project Evaluation

As outlined in the module, project evaluation should be based on principles such as:

Performance Appraisal Systems

Many companies establish methods to improve employee performance and correct errors. Performance appraisal systems are well-established in organizations. Information gathered by these systems is used to decide wage adjustments, promotions, and training. Managing and evaluating performance remains a challenge for most managers. Performance management is the process of linking individual or group performance with the main strategic mission and values.

Objectives of Performance Management Systems

• Motivate Performance: Employee motivation and performance are key factors for business success. Owners and managers strive for good performance.
• Aid Continuous Improvement: Performance management systems help identify areas for

System Development Life Cycle (SDLC)

The System Development Life Cycle (SDLC) is a conceptual model used in project management. It describes the stages involved in an information system development project, from an initial feasibility study through maintenance of the completed application. Various SDLC methodologies have been developed to guide the processes involved, including the waterfall model, rapid application development (RAD), joint application development (JAD), the spiral model, prototyping model, and build and fix model.

Most organizations have a formal system development process consisting of a standard set of processes or steps they expect will be followed on any system development project. While these processes may vary greatly...
