Professional Background and Technical Skills

I have always been interested in how technology can be used to improve businesses, especially the decision-making process. I studied Computer Science at university, and through my personal and capstone projects, I realized I enjoy the process of turning messy data into structured information where valid and accurate insights make a meaningful impact.

I also completed an IT co-op where I supported end users of various technical backgrounds, giving me the ability to explain technical concepts to non-technical users in a simple manner—a skill I know would be valuable in this role, mainly when dealing with clients. I am also familiar with Excel, SQL, and Tableau, skills I know would translate well into... Continue reading "Alpha EPM Interview Preparation and Career Strategy" »

Office Layout and Administrative Foundations

Defining Office Layout and Its Objectives

Office layout refers to the physical arrangement of office furniture, equipment, departments, and staff within the available office space. It involves the systematic planning and organizing of workspaces to ensure smooth workflow, better communication, and optimal use of space. A well-designed office layout creates a professional environment and enhances the overall efficiency of the organization.

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... Continue reading "Operations Management Concepts: Forecasting, Quality, and Inventory" »
