A LITTLE BIT ABOUT ME
Dear friends, welcome to advice4diabetes.com. By creating this web site I was inspired by my friends and my family who believe me, support and encourage in my journey. Without my friends, it will be impossible to create this website.

HUMAN FACTOR RESEARCH
THE PART # 1. HUMAN FACTOR RESEARCH
STEP 1: PRELIMINARY ANALYSIS
Working with people to “better understanding who are users, what are their needs, and kind of environment they use” (Schaeffer, 2012). This phase included analysis of user interface.
STEP 2: FORMATIVE EVALUATION AND DESIGN MODIFICATION
The formative evaluation and design modification involved usability testing. “The primary focus was on safety and usability of the product design” (Schaeffer, 2012). This part of research was involved 5-
Researchers observed participants’ behaviour when they performed the task. One of the most important of formative evaluation is to prove that t:slim design is safe for human use.
STEP 3: VALIDATION TESTING
This is the last part of study to confirm safety of the insulin pump. Study included both people with diabetes being treated with multiple injection and people who were on the insulin pumps. “Evaluation is done on the comprehensive realistic set of basic and advanced task-
Based on my description above Tandem used human factor research for developing safe insulin pump. None of the insulin pump companies published research papers when they developed their insulin pump. Shame.
In my opinion, one of the minuses of Tandem was excluding people who were using omnipod system. It doesn't matter if you are pumping with pump, which has infusion set and people who are using patch pump or wireless. I'm sure behind this tandem has the different opinion. What I admire tandem diabetes care research group that they did comprehensive research work. I'm impressed with engineers and computer programmers who work on developing t:slim. The t:slim insulin pump is completely different from other insulin pumps in design, form, and touch screen.
This is the introduction about research of developing t:slim insulin pump. I will add more statistical data shortly.

Human Factor Research in the Design and Development of t:slim insulin pump
Tandem Diabetes Care Inc developed t:slim insulin pump by utilizing human factor research. The human factor research was never used before by insulin pump companies.
Human factor is a discipline, which studies behaviour of the end – user and way the human interacts with equipment. It includes many studies such as psychology, engineering, design, statistics, ethnography (is a qualitative research design aimed at exploring cultural phenomena) (Ethnography, 2013)and anthropometry refers to the measurement of the human individual (Schaeffer, 2012). Two articles have been published in Diabetes Technology & Therapeutics that describe t: slim insulin pump based on human factor research. Both articles were written by Noel Schaeffer Ph.D, who works for Tandem Diabetes. He is holding position as Senior User Experience Researcher II at Tandem Diabetes Care. According to Noel Scheffer the human factor process includes three primary phases:
NEW APPROACH IN DESIGNING MEDICAL DEVICES:
1. Preliminary analysis
2. Formative evaluation and design modification
3. Validation testing
