Requirements are the descriptions of the software system, its desired features, and targeted functionalities. They can be divided into functional and non-functional requirements. Functional requirements are what the users expect from the proposed product, and non-functional requirements relate to aspects like the look, performance, security, and user-interface. There is a wide variety of tools available for gathering and managing software requirements in the market. The selection is based on the methodologies and goals and differs from project to project.
Nevertheless, the first step in the tracking process is to list the requirements and create an Excel sheet with details like type, dependency, priority, etc.
Modularization divides the software system into discrete modules. Here, every module is expected to carry out specified tasks independently. Cohesion measures and defines the intra-dependability among the different elements of a module. A project manager is tasked with responsibilities like project planning, progress monitoring, and communication. The software scope includes all the activities required to deliver a software product.
It defines the following aspects to streamline the development process:. A feasibility study helps measure the practical benefits that a software development project may bring to an organization.
Software analyzers consider three main factors before preparing their final report. We have explained them in detail below:. The software analysis and design procedures help translate requirement specifications into implementation. Here are some standard tools:. It includes programming language keywords. In contrast, the Pseudo Code methodology closely resembles the programming language but without any specific syntax. You can calculate the software size by calculating the lines of delivered code or the function points.
Function points are considered a relevant measurement as they represent the features offered by a software product. Software metrics refer to the measurements of the requirements and the product itself.
Project estimation is an integral part of sound software project planning. Here are some widely-used methods:. The review of software implementation would entail activity monitoring, milestone checklists, and status reports. Project management tools provide a comfortable way of checking progress. Configuration management is about tracking and controlling changes in a software project. It is vital to maintain the consistency of the software system with organizational rules and regulations.
Quality assurance checks are done to find out whether the proper development process was followed. On the other hand, quality control is concerned with maintaining the quality of the end product. Compare Interface-oriented, Object-oriented, and Aspect-oriented programming.
Interface programming is a contract-based architectural pattern applied for achieving modular design at the component level. Object-oriented programming deals with writing granular objects having a singular purpose.
Aspect-oriented programming aims to segregate the code so that multiple objects carry the main tasks and independent objects carry the subsidiary tasks. A class containing an abstract keyword in its declaration cannot be instantiated. It is best to declare a class as abstract in the situations mentioned below. However, the converse is not possible.
It is heavier and requires more context-switching. A single program can have more than one thread. That balance is a business decision as opposed to a technical one. Rather, I come up with some potential alternatives and present their impact on that balance. For example, if an impediment may significantly push delivery beyond what was projected, I might present an alternative that can meet the current timeline with much of the same scope but will likely diminish the quality and degrade the user experience.
This collaborative process ensures that all parties are confident in the final decision. Retention is a high priority for many employers. Replacing a team member can be quite expensive in cost terms of recruitment and training time. Asking questions to ensure your interests and motivations align with that of the company can reduce the risk of losing you as a team member.
Example: "I was watching an interview with your CEO about your product that aims to disrupt the lending industry. Streamlining arduous tasks like loan applications has huge potential. I think the growth in this sector over the last year is a big indication of things to come.
I see this as giving your company the competitive advantage in this space as the verifiable auditability will reduce compliance costs. Employers want to know that you are thinking beyond the technical aspects and aim to solve real-world problems.
This often comes down to identifying a metric to improve and creating a testable hypothesis of your expected project impact. Example: "Before a project is even started, success metrics are laid out. I will identify the key performance indicator KPI that we are hoping to impact and begin gathering information to formulate ideas.
These ideas are stated as a falsifiable hypothesis. Here are some additional questions grouped by category that you can practice answering in preparation for an interview:. Some questions you may face in a software engineer position interview are general. The purpose of these questions is to get to know more about your personality and how you could fit in the workplace culture, such as:. What were your main responsibilities in your previous job?
When was the last time you were in a crunch? What could have prevented the situation and what changed to avoid it in the future? Why should we hire you as a software engineer on our team? What are your favorite software engineering books and why? How do you work independently and as part of a team? Which do you prefer? What are your greatest strengths and weaknesses? Describe a time you overcame a non-technical obstacle at work. In addition to the general questions, a hiring manager could ask, you will likely also need to answer questions about your background and experience in the software engineering industry.
These questions will allow you to elaborate more on the skills you have gained through your education and work experience. Describe your process for completing a project from start to finish. What scaling issues have you had to deal with on past projects? How could it have been avoided and how did you solve it? Tell me about a time that you had to collaborate with other people on your team or other teams to solve a complicated problem. Describe the process your team currently implements for completing projects.
What works well? What would you change and why? Which project management tools do you feel are most useful in your role as a software engineer? An interviewer may ask questions that allow you to showcase your knowledge regarding specific aspects of the role, such as:.
What are your favorite software development tools? How much do you code daily in your current role? What differentiates a good software engineer from a great one? Describe what you believe are the key principles of software engineering. How comfortable do you feel reviewing code written by others?
What process do you follow when reviewing someone else's code? Find jobs. Company reviews. Find salaries. Upload your resume. Sign in. The level of coupling between two modules depends on the complexity of the interface.
For more details, please refer to the following article Coupling and cohesion. What are the various phases of SDLC? What is the name of various CASE tools?
What is Black box testing? The black box test also known as the conducted test closed box test opaque box test is centered around software useful prerequisites. In other words, it is possible to guess a set of information conditions that help the program through an attempt to discover and fulfill all the necessities perfectly.
There is no choice of black-box testing white box procedures. What is White box testing? White Box Testing is a method of analyzing the internal structure, data structures used, internal design, code structure, and behavior of software, as well as functions such as black-box testing.
Also called glass-box test or clear box test or structural test. What is a Feasibility Study? The Feasibility Study in Software Engineering is a study to assess the adequacy of proposed projects and systems. A feasibility study is a measure of a software product on how product development can benefit an organization from a validity analysis or practical point of view. For more details, please refer to the following article Types of Feasibility Study in Software Project Development article.
It focuses on fulfilling the quality requested. It is the technique of managing quality. It is the technique to verify quality. It does not include the execution of the program. It always includes the execution of the program. It is a managerial tool. It is a corrective tool. It is process-oriented. It is product-oriented. The aim of quality assurance is to prevent defects. The aim of quality control is to identify and improve the defects.
It is a preventive technique. It is a corrective technique. It is a proactive measure. It is a reactive measure. It is responsible for the full software development life cycle. It is responsible for the software testing life cycle. Example: Verification Example: Validation What is the difference between Verification and Validation?
Verification Validation Verification is a static practice of verifying documents, design, code, black-box, and programs human-based. Validation is a dynamic mechanism of validation and testing the actual product. It does not involve executing the code. It always involves executing the code. It is human-based checking of documents and files.
It is computer-based execution of the program. Verification uses methods like inspections, reviews, walkthroughs, and Desk-checking, etc. Validation uses methods like black box functional testing, gray box testing, and white box structural testing, etc. Verification is to check whether the software conforms to specifications. It can catch errors that validation cannot catch.
It can catch errors that verification cannot catch. Target is requirements specification, application and software architecture, high level, complete design, and database design, etc. Target is an actual product-a unit, a module, a bent of integrated modules, and an effective final product. Verification is done by QA team to ensure that the software is as per the specifications in the SRS document.
Validation is carried out with the involvement of the testing team It generally comes first done before validation. It generally follows after verification.
It is low-level exercise. It is a High-Level Exercise. For more details, please refer to the following article Software Engineering — Verification and Validation.
What is reverse engineering? Software Reverse Engineering is a process of recovering the design, requirement specifications, and functions of a product from an analysis of its code. It builds a program database and generates information from this. The purpose of reverse engineering is to facilitate maintenance work by improving the understandability of a system and producing the necessary documents for a legacy system.
Reverse Engineering Goals: Cope with Complexity. Recover lost information. Detect side effects. Synthesize higher abstraction. Facilitate Reuse. For more details, please refer to the following article Software Engineering — Reverse Engineering.
What is SRS? Software Requirement Specification SRS Format is a complete specification and description of requirements of the software that needs to be fulfilled for successful development of software system.
These requirements can be functional as well as non-requirements depending upon the type of requirement.
