Summary

An overview of the software development lifecycle and its phases.

What is the Software Development Lifecycle?

The software development lifecycle (SDLC) is a process used by software developers to design, develop, and maintain software applications. It consists of several phases, including planning, analysis, design, implementation, testing, deployment, and maintenance.

Phases of SDLC

  • Planning: Defining the scope and purpose of the project.
  • Analysis: Gathering requirements and analyzing user needs.
  • Design: Creating the architecture and design of the software.
  • Implementation: Writing the code and building the software.
  • Testing: Verifying that the software works as intended.
  • Deployment: Releasing the software to users.
  • Maintenance: Ongoing support and updates.

Understanding the SDLC is essential for successful software development.

FAQs

What if I don’t have an accepted form of ID?

While you'll need one of our accepted forms of ID to complete verification, you can take your time gathering the right documents. The verification process is ready whenever you are.

What skills do I need to apply?
  • We are looking for workers with a strong command of the English language, including spelling and grammar skills. Research, fact-checking and critical thinking and analysis skills are critical to be successful.
  • For coding projects, you will need to be proficient in at least one programming language (Python, JavaScript, HTML, C++, C# or SQL) and able to solve coding problems (think LeetCode, HackerRank, etc) and explain how your solution solves the problem.
What if the address on my ID doesn’t match my current address?

As long as you have been associated with the address listed on your ID, that’s fine.

What happens to my data once I provide my ID?

Your information, including your biometric data, is stored by DataAnnotation and Persona, the identity verification service provider, for purposes of identity verification only. Your data is stored on secure servers with strict access controls and monitoring. For more information on how your data will be kept secure, please consult the Persona identity verification Privacy Policy, as well as DataAnnotation’s Privacy Policy.

How do I get paid?

It is very important that you provide the correct email address associated with your PayPal account. If you do not have a PayPal account, you will need to establish one with an email address that you use.
