Theme #5. Reflection

Last week we had two lectures. The first lecture covered following questions: how to come up with idea, how to define the problem, how to solve the problem, how to evaluate, validate and communicate the idea. I found the lecture very interesting as we consider the process from generation ideas to bringing it in practice in depth.
The summary of lecture helped me to understand main idea aspects: generation idea, filtering idea, validation idea, evaluation idea and communication the idea.
The main conclusions that I made after the lecture:
1. Defining problem is the key thing to come up with the idea.
2. There are 5 questions formulated by Cisco company to define how innovative the idea:
   • Does it address a real pain point?
   • Will it appeal to a big enough market?
   • Is the timing right?
   • If we pursue the idea, will we be good at it?
  • Can we exploit the opportunity for the long term, or would this market commoditize so quickly that we wouldn’t be able to stay profitable? (https://hbr.org/2009/09/inside-ciscos-search-for-the-next-big-idea)
3.Three components of idea validation – proof of concept, existing of potential customers and fund to realize the idea.
The second lecture develop and support points from the previous lecture. The topic was design research. The aim of design research is to shape prototype to answer the particular question. So in other words, prototyping is used to solve the problem. But prototype as it is, is not a decision, it can be a way to generate empirical data that we don’t have to obtain the solution of claimed problem/question of the research. The teacher explained how to used design method and role of prototype using example of research papers for this lecture.
Definition and meaning of prototype was not really clear for me, that’s why I checked additional sources of information.
In dictionaries prototype means an original model on which something is patterned, a standard or typical example, a first full-scale and usually functional form of a new type or design of a construction. So basically synonym word of prototype is pattern. How is it related to the research? The answer I found in the article by “Prototyping as a powerful tool in a user centered innovation process” Tiago Barros and Paulo Melo. “Prototyping is important to bring abstract ideas to a more concrete level […] While prototyping, developers face several limitations that could not be identified while they were discussing abstract concepts only. Apart from that, prototypes bring light to new aspects and opportunities that have not been considered.” I think that, on the one hand, prototype is interim step to prove the feasibility of suggested concept, on the other hand, prototype is base for further investigation and probably new hypothesis as it was mentioned above “prototypes bring light to new aspects and opportunities.” So prototype testing is crucial for exploring limitations and making appropriate changes.

Theme #6

I have selected the research paper “Don’t be dumb—that’s the rule I try to live by”: A closer look at older teens’ online privacy and safety attitudes” by Denise E Agosto and June Abbas published in New Media and Society, impact factor 2.007.
The goal of the research is to investigate problem of online safety and online privacy in social networks and teenagers’ concerns about it. Authors used qualitative methods to research the topic in-depth. The results showed responsible attitude and behavior of younger generation in terms of online privacy, and less awareness of online safety.

1. Which qualitative method or methods are used in the paper? Which are the benefits and limitations of using these methods?

Qualitative methods used in that paper includes questionnaire and interview of focus group.  The research was conducted in two steps. Participants are 18-19 age male and female students of U.S. public school, total 98 people. The first step is questionnaire that includes such questions as age, sex, race, computer and phone ownership, frequency of using social networks.The second part is interviewing of focus group to concretize answers.

2. What did you learn about qualitative methods from reading the paper?

I already known about qualitative methods such as questionnaire, interview and focus group, but it was interesting for me to know about “qualitative content analysis method” that the authors used for data analysis. The interview answers of focus-group were recorded, obtained transcripts were analyzed according to that method in order to define thematic categories by inductive development method. Conclusions were made according to defined categories relying on particular answers from focus group.

3. Which are the main methodological problems of the study? How could the use of the qualitative method or methods have been improved

The limitations of the study are that research results are not applicable for all teens age categories as behavior 13-14 years old teenagers and 18-19 is different, so the results are actual for older teenager group. The second limitation is that attitude and behavior in social networks can change with time very fast. For instance, if the research was conducted several years ago in the begging of “social networks era”, the results would be different, since the subject of the study relates to fast developing and widely used technologies.

I have selected case study “Intercultural Communication Training in IT Outsourcing Companies in India: A Case Study” by Raju, R. from IEEE organization journal.
The aim of the research is to investigate the reasons of communication problems in international outsourcing companies. The research is based on case study conducted US outsourced business in India. The author used such qualitative methods as personal interview and group interview, and quantitative date gathered from the survey. Obtained results define the reason of communication problem as lack of training, solution proposed by participants of case study are included in the research.

1. Briefly explain to a first year university student what a case study is

Case study is the method of qualitative research that implies in-depth and detailed analyzing of one particular subject. The case study is a research strategy which focuses on understanding the dynamics present within single settings. (Eisenhardt, K. M. (1989). Building Theories from Case Study Research. Academy of Management Review, 14(4), 532-550) Case study either is based on questionnaire, if crucial question has emerged, or identify the research question that is used in questionnaire to get more general results. Following characteristics of case study can be defined: focusing on one subject instead of multiply ones, aims to understanding instead of explanation, using not manipulative data, ambiguous results are acceptable, multiply perspectives are considered. (“Case study”, Denis Hayes, http://www.edu.plymouth.ac.uk/resined/Case_study/casest.htm)

2. Use the "Process of Building Theory from Case Study Research" (Eisenhardt, summarized in Table 1) to analyze the strengths and weaknesses of your selected paper.

Selected research paper meet all steps of "Process of Building Theory from Case Study Research".
The author clearly defined the research question – reasons of communication problem in outsourcing company. Author references on similar study, use both quantitative and qualitative methods. Data analysis was conducted using Anova and t-tests, interviews were categorized, the Geisler's techniques was applied to code and analyze the data. Received results proves possibility to apply Cross Theory to communication issues, but they are not the basement of new theory. But I don't think that it's weak side of research as not every research should build the new theory.

Seminar #4. Refection

The theme of qualitative and quantitative methods was quite easy for me as I already know about it and used in my Bachelor thesis.  Other students in our seminar groups also were aware of qualitative and quantitative methods, so we discussed our bachelor thesis mostly.

In my thesis I used quantitative methods since I developed decision to analyzing target audience and seasonal trends in touristic agency. I analyzed sample and used statistic methods. Another members of our group used such qualitative methods as interview and questionnaire. So it was very interesting to share experience and know about research subjects of each other.

Then we discuss the advantages and disadvantages of qualitative and quantitative methods. We all agreed that key reason to decide what methods are more effective is subject of research. For example, qualitative methods are widely used for sociological and anthropological studies. In that case such qualitative methods as interview, questionnaire, and case study allow to analyze human behavior deeply while quantitative methods allow to get more general results.


After this seminar I learnt more about qualitative methods and how they can be applied in different studies.

Theme #5 Part 2

1.     What is the 'empirical data' in these two papers?
In the first paper (Fernaeus & Tholander) data was collected using prototype. In the second paper (Lundström) data was collected by interviewing and using prototype as well. Also author analysed information gathered from online forums.
2.     Can practical design work in itself be considered a 'knowledge contribution'?
Knowledge contribution means creation new knowledge relying on previously known facts. In my opinion practical design can be considered as knowledge contribution. Practical design is created to solve certain problem, but proposed decision can be base for further research in the same or contiguous areas depending on results and conclusions that can be made using practical design.
3.     Are there any differences in design intentions within a research project, compared to design in general?
In my opinion design intentions within a research paper aim to answer certain questions, prove hypothesis and are intended to influence on research subject or supplement it in certain way. Basically design within research project has contribution on knowledge. Design in general can be aim to satisfy users’ needs, or has just commercial application and don’t have contribution on knowledge.
4.     Is research in tech domains such as these ever replicable? How may we account for aspects such as time/historical setting, skills of the designers, available tools, etc? 
I think that development of technology made research replicable. For instance, it’s possible to use the same software, tools, and approaches. On the other hand, the same research cannot be replicate in another period of time due to new theories and new knowledges. Designers skills are very individual and if we are talking about design that needs exclusively human skills it would be impossible to repeat it.
5.     Are there any important differences with design driven research compared to other research practices?

I think that the main difference is that design driven research is based on observation of users’ behavior and it uses qualitative research methods.   

Theme #5 Part 1

1.     How can media technologies be evaluated?
In this paper proposed method of media technology (experimental system) can be evaluated by several key points.
Users satisfaction – how users are comfortable with using system. Users satisfaction can be measured by questionnaire.
Efficiency – how much time and efforts the system requires to complete the task.
Effectiveness – how the system works, can be evaluated by calculation number of errors in particular period of time.

2.     What role will prototypes play in research?
Prototype as preliminary version of final product plays significant role in research. Final product is based on prototype, but can have additional facilities and improved functions. Prototype is tested in different conditions in order to reach perfect combination of functions, facilities, etc., of final product.  

3.     Why could it be necessary to develop a proof of concept prototype?
A proof of concept (POC) or a proof of principle is a realization of a certain method or idea to demonstrate its feasibility (Investorwords.com) . Therefore developing of a proof of concept prototype is necessary to prove the implementability and capacity of final decision (product). Proof of concept allows to probably change the direction of research before creating prototype, if, for example, feasibility is not reached.

4.     What are characteristics and limitations of prototypes?
There are pragmatic and practical limitations to the ability of a prototype to match the intended final performance of the product and some allowances and engineering judgments are often required before moving forward with a production design (Modelling and Simulation Fundamentals. John A. Sokolowski, ‎Catherine M. Banks). 
Investigation of prototype’s limitation allows to develop certain characteristics of final product. The goal is to understand the limitations of prototype and to lower the risk of failure of final model. So limitations of ability to match prototype with intended product have to be studied before developing the final product.

5.     How can design research be communicated/presented?
Design research presentation depends on subject of research. I think that design can be presented by prototype, sketches, photos, videos.
