This protocol document is structured as a list of topics that we intend to cover in our interviews of software engineers at Costco. The questions listed under each topic are illustrative of the kinds of questions we plan to ask, but by no means exhaustive. We are conducting a research study to learn about the architectural evolution of software systems at Costco. Your participation in this research is completely voluntary, and you may withdraw from the study at any time. With your permission, I will collect your name and contact information so that I can contact you later if I have follow-up questions. You should avoid using first names or specific names when providing information for this study.
The audio recording will be kept private, so that only my research advisor and I have access to it. Would you mind giving me your name, e-mail address, and phone number? If the participant does not wish to provide complete contact information, but does wish to continue the interview, proceed without collecting information. Are there particular tasks involved in planning an architecture evolution that you think are especially suitable for buy custom term papers automation? The following questions illustrate the kinds of questions we will ask, although the specific systems and components named in these sample questions are fictitious. Do you have any other questions for me about my research or this case study? No coding unit may be left uncategorized, and two categories may not be assigned to a single coding unit. In selecting a category for a given coding unit, consider the coding unit itself as well as its immediate context—up to a couple of paragraphs before and after the coding unit. These may be stated in terms of goals of the target system (e.
This category may be applied regardless of whether the evolution described is one that has already happened, one that may yet occur, or one that was considered but not carried out. Add features Description: This category should be applied when an aim of Abbreviation: mot-fea evolution is to implement new functionality or new features. The line between a new feature and a quality improvement can sometimes be fuzzy.
This category should be applied when flexibility in general is described as a goal— when an evolution is described as aiming to open up future possibilities generally. And an opportunity had been presented to us to update to an object-oriented system that would provide some flexibility for anything that we might choose to do someday. Description: This category should be applied to evolution motives that do not fit into design and technology gcse coursework any of the other categories. Residual categories such as this should be used only when none of the specific categories fit. Causes of problems Abbreviation: cau Description: Subcategories of this category should be applied to descriptions of circumstances that caused problems during the course of an evolution project.
These are people who have seen one way of doing things. They piloted new e-comm and web software a week before Black Friday— the Friday after Thanksgiving.
Residual categories such as this should be used only when none of the specific categories fit. Consequences Abbreviation: con Description: Subcategories of this category should be applied to adverse consequences that arose due to missteps in an evolution project. Lost sales Abbreviation: con-sal Description: This category should be applied when problems during an evolution resulted in financial loss. Residual categories such as this should be used only when none of the specific categories fit. This category should also be applied to discussions of the difficulty of training people or the difficulty of learning new technologies.
We are trying to change so much in such a short time. I was telling somebody the other day, just go google system context diagram, and see how many flavors of that you get: like a thousand different models. Description: This category should be applied to challenges that do not fit into any of the other categories. Residual categories such as this should be used only when none of the specific categories fit. This includes everything from formal processes to very informal rules of thumb. In addition, some of the subcategories of this category are rather broad buy custom term papers topically. As a result, subcategories of this category will often apply to quite long segments of text, to a greater degree than is true of the other major categories, which usually apply to shorter passages, rarely longer than a few sentences. Experience and Description: This category should be applied to descriptions of intuition architects relying on their own experience, intuition, or judg- Abbreviation: app-int ment to make evolution decisions, or of architects learning from their experiences. Each evolution basically took on a chunk of our scope. So what we ended up doing is looking at business capability from the business architecture team. As we modernize those, then we look to buy custom term papers that future where they all have an interaction with each other. Residual categories such as this should be used only when none of the specific categories fit. The other main categories are applicable to coding units that describe architectural elements.
Because the coding units in this content analysis are not contiguous—each coding unit consists of a set of isolated fragments of content spread throughout the data— substantial surrounding context may be necessary to accurately categorize a coding unit. This surrounding context certainly extends to each page on which the coding unit occurs in the architectural documentation, as well as a couple of paragraphs before and after each occurrence of the coding unit in the interview transcripts.
In a few cases where categorization is particularly difficult, it may be appropriate to go beyond the research data and consider external sources of buy custom term papers information. The external documents listed above should be used only as necessary to settle close calls in cases of ambiguity.
