**Methodology** refers to the systematic and structured approach used to conduct research or solve a problem. It involves the:
* **Design**: planning and organization of the research or project
* **Methods**: techniques and tools used to collect and analyze data
* **Procedures**: steps taken to implement the research or project
* **Tools**: instruments, software, or equipment used to support the research or project

A good methodology should be:
* **Clear**: easy to understand and follow
* **Systematic**: logical and organized
* **Valid**: based on sound principles and assumptions
* **Reliable**: consistent and dependable

In research, methodology is crucial because it:
* **Ensures consistency**: in data collection and analysis
* **Minimizes bias**: by using objective and systematic methods
* **Increases validity**: by using reliable and valid methods
* **Enhances credibility**: by demonstrating a systematic and thorough approach

Some common research methodologies include:
* **Quantitative**: numerical data collection and analysis
* **Qualitative**: non-numerical data collection and analysis
* **Mixed-methods**: combination of quantitative and qualitative approaches
* **Experimental**: controlled experiments to test hypotheses
* **Survey**: data collection through questionnaires or interviews

In your field of BSIT, methodologies can be applied to:
* **Software development**: using Agile, Waterfall, or other development methodologies
* **Data analysis**: using statistical, machine learning, or data mining methodologies
* **System design**: using human-centered, user-centered, or systems thinking methodologies

Here are some **key considerations** when selecting a methodology:
* **Research question**: what question or problem are you trying to address?
* **Data type**: what type of data will you be working with (quantitative, qualitative, or both)?
* **Resources**: what resources (time, budget, personnel) are available for the project?
* **Goals**: what are the goals and objectives of the project?
