What are the steps in the SDLC methodology?
- Answer
-
The steps in SDLC are planning, analysis, design, implementation, and maintenance.
What is RAD software development?
- Answer
-
RAD is a development methodology focused on quickly building a prototype and iterating based on user feedback instead of detailed specifications.
What is the Waterfall model?
- Answer
-
The Waterfall model is an SDLC-based model with sequential phases of requirements, design, implementation, testing, and maintenance.
What makes the lean methodology unique?
- Answer
-
The lean methodology is unique in its focus on launching a minimum viable product quickly and using user feedback to iteratively modify it.
What is the difference between the Waterfall and Agile models?
- Answer
-
Waterfall uses sequential phases while agile utilizes iterative sprints and continuous user feedback.
What is a sprint?
- Answer
-
A sprint is a short, fixed time period in agile development during which specific features are implemented.
What are three differences between second-generation and third-generation languages?
- Answer
-
Three differences are: 2GLs are low-level/machine code, 3GLs are closer to human language, 3GLs are portable across platform.
Why would an organization consider building its own software application if it is cheaper to buy one?
- Answer
-
Reasons to build vs buy include greater customization, competitive advantage, and keeping intellectual property in-house.
What is the difference between the pilot implementation methodology and the parallel implementation methodology?
- Answer
-
Pilot rolls out to a subset of users first, while parallel runs new and old systems concurrently for everyone.
What are the differences between compiled programming languages and interpreted programming languages?
- Answer
-
Compiled languages are converted to machine code before execution. Interpreted languages are executed line-by-line by an interpreter program.
What is change management?
- Answer
-
Change management is the process of managing user adoption when introducing a new system through training, support, and communication.
What are the four different implementation methodologies?
- Answer
-
Direct cutover, pilot, parallel, and phased are four implementation methodologies.
Exercises
- Which software-development methodology would be best if an organization needed to develop a software tool for a small group of users in the marketing department? Why? Which implementation methodology should they use? Why?
- Doing your own research, find three programming languages and categorize them in these areas: generation, compiled vs. interpreted, procedural vs. object-oriented.
- Some argue that HTML is not a programming language. Doing your own research, find three arguments for why it is not a programming language and three arguments for why it is.
- Read more about responsive design using the link given in the text. Provide the links to three websites that use responsive design and explain how they demonstrate responsive-design behavior.
- Discuss advantages and disadvantages of buy vs build.
- Research the criteria and cost to put a mobile app into Apple’s App Store. Write a report.
- Consider Google Docs or Google Sheets. What end user application - add on would you make it more productive or convenient for your use?
- Research to find out what elements to use to estimate the cost to build an app. Write a report.
- Go to a job site and find a software developer job description. What are the required qualifications and skills?
- Install and try a simple new software application, from a credible source, on your computer or phone. Document your experience going through the implementation and adoption process.
- Sign up for a free trial of an online software service like project management, email marketing, or accounting. Evaluate their onboarding and training process for new users.
- Observe someone who doesn't have a technical background use a new software tool. Note any difficulties they encounter and where the product could be more user friendly.
