This document discusses research methods and designs. It defines quantitative and qualitative research methods. Quantitative methods use numerical data and statistics, while qualitative methods focus on patterns and human experiences. The document also outlines different types of research designs, including descriptive, experimental, quasi-experimental, correlational, narrative, phenomenological, grounded theory, historical, case study and ethnographic. It provides examples of how to create a research method and an example research method related to constraint identification and classification.

3. Research Method
Methods of Research are the approach to conduct a study
and specific procedures for collecting and analyzing data.
These can either be qualitative or quantitative.

4. Quantitative
-examines numerical data and often requires the use of
statistical tools to analyze data collected.
-It can use to wider population
Qualitative
-non-numerical and focuses on establishing patterns.
-does not use numbers and statistics.
-use human experiences, beliefs, behavior
-gathered in written format as opposed to numerical
-Works with small participants

5. Research Design
Framework of the methodologies and a plan that a
researcher use in order to answer the research question

6. Quantitative Types
express a population, situation or phenomenon.
answer questions of what, where, when and how, but
not questions that asks why
Descriptive
Relies on statistical analysis to prove or disprove the
hypothesis making it the most accurate form of research.
It involves manipulating the independent variables by
randomly distributing it to dependent variables to
measure its impact on the said dependent variable.
True-Experimental

7. Quantitative Types
Similar to True experimental
The research subjects already assigned in groups since
the event has already happened.
Causal-Comparative/Quasi-Experimental
establish the extent of relationship using statistical data
and investigates if there is any correlation identified
between the variables.
It can be positive or negative
Correlational

8. Qualitative Types
to investigate and conceptualize the human experience
You tell a story based on your observation
uses stories and storytelling as a source of knowledge
Narrative
perspectives of persons who have experienced a
phenomenon
to understand the universal nature.
Phenomenological

9. Qualitative Types
inductive (specific to general) approach that offers
systematic guidelines for gathering, synthesizing,
analyzing, and conceptualizing qualitative evidence.
Grounded Theory
historical research analyzes the importance, meaning,
and cause of past events and their effect on present or
current event.
Historical

10. Qualitative Types
detailed study of an individual who is involved in societal
or social issues.
Case study
study of people in their real-life environments
culture and values
Ethnography

2
Conduct a thorough analysis of the relevant
literature and current procedures in the field.
Engage in ideation to consider a variety of potential
methods for the research topic.
3 Develop hypotheses, research questions, or
determine pertinent factors.
4 Carefully choose the best operationalization
techniques for the selected research strategy.

Apply data gathering methods, such as surveys,
interviews, and observations.
Select suitable sample strategies and statistical
techniques.
7 Be aware of potential problems and issues
throughout the study process.
8 Be open to changing the research strategy, data
collection methods, or analytical methods.

Research Method
The primary research method for this study is literature review and conceptual modeling.
Constraint identification and classification through a structured approach is the very first
step toward a “zero-constraint” environment. This study will first review various types of
constraints in construction and their characteristics. Based on this understanding, a
classification method will be developed to categorize constraint factors for the purpose of
constraint identification and modeling. In the second stage of this study, existing constraint
modeling methods will be identified based on a comprehensive review of current industry
practices and academic researches. Finally, once the constraint classification and modeling
techniques are identified, a conceptual framework for total constraint management will be
outlined. This study will be conducted between September 2010 and May 2011.
