How software is built and managed ?

 Building and managing software is a structured process that involves several stages, practices, and roles. Here’s a breakdown of how software is typically built and managed, from idea to deployment and maintenance:

🏗️ How Software Is Built

1. Planning and Requirements Gathering

  • Goal: Understand what needs to be built.

  • Activities:

    • Stakeholder interviews

    • User research

    • Define functional and non-functional requirements

    • Create a product roadmap

2. Design

  • Goal: Architect the system and user experience.

  • Activities:

    • UI/UX design (wireframes, mockups, prototypes)

    • System architecture (how components interact)

    • Database schema design

    • Choose technologies (e.g., frontend, backend, cloud)

3. Development

  • Goal: Write the code that makes the software work.

  • Activities:

    • Frontend development (user interface)

    • Backend development (server-side logic)

    • API development

    • Integrate databases

    • Version control (e.g., Git/GitHub)

4. Testing

  • Goal: Ensure the software works as intended.

  • Types of Testing:

    • Unit testing (individual components)

    • Integration testing (components working together)

    • End-to-end testing

    • Performance/security testing

    • User Acceptance Testing (UAT)

5. Deployment

  • Goal: Release the software to users.

  • Tools and Practices:

    • CI/CD pipelines (automated testing + deployment)

    • Containerization (e.g., Docker)

    • Cloud services (e.g., AWS, Azure)

    • Monitoring setup (logs, alerts)

⚙️ How Software Is Managed

1. Project Management

  • Methodologies: Agile (Scrum, Kanban), Waterfall, DevOps

  • Tools: Jira, Trello, Asana

  • Practices:

    • Sprint planning

    • Daily stand-ups

    • Sprint reviews and retrospectives

2. Version Control

  • Tools: Git, GitHub, GitLab, Bitbucket

  • Practices:

    • Branching strategy (e.g., Git Flow)

    • Pull requests and code reviews

    • Continuous Integration (CI)

3. Team Collaboration

  • Tools: Slack, Microsoft Teams, Notion, Confluence

  • Practices:

    • Documentation

    • Knowledge sharing

    • Cross-functional teams

4. Quality Assurance (QA)

  • Ongoing testing during and after development

  • Bug tracking and fixing

  • Regression testing before each release

5. Monitoring and Maintenance

  • Tools: Datadog, New Relic, Prometheus, Sentry

  • Activities:

    • Monitoring performance, uptime, and errors

    • Updating dependencies

    • Addressing user feedback

    • Patching security vulnerabilities

6. Scalability and DevOps

  • Automate infrastructure (Infrastructure as Code, e.g., Terraform)

  • Load balancing, caching, database replication

  • Horizontal/vertical scaling

🧑‍🤝‍🧑 Roles Involved

  • Product Manager: Defines what to build and why

  • Project Manager: Coordinates timelines and resources

  • Software Developers: Build the software

  • Designers: Create user interfaces and experiences

  • Testers/QA Engineers: Ensure software quality

  • DevOps Engineers: Manage deployment and infrastructure

  • Support Engineers: Handle issues post-release

One smart genius move that made Bill gates a Billionaire.

  🔥 Great question — and while Bill Gates made many smart moves , there's one genius decision that truly changed everything and put him on the path to becoming a billionaire: 💡 The Genius Move: Licensing MS-DOS to IBM Without Giving Up Ownership 📜 The Story in a Nutshell: In 1980, IBM was building its first personal computer. They needed an operating system (OS). IBM approached Microsoft (a small company then) — but Microsoft didn’t even have an OS at the time! So what did Gates do? 🧠 Bill Gates’ Genius Play: He didn’t sell the OS — he licensed it. 👉 This meant Microsoft kept the rights to it and could license it to others later too. He got the OS (QDOS) from another company (Seattle Computer Products), tweaked it, and called it MS-DOS . He delivered MS-DOS to IBM, who bundled it with their PCs. As IBM PCs exploded in popularity, MS-DOS became the default OS — and Microsoft got paid every time. 💰 The Impact: Microsoft wasn’t just tied to IBM ...

Expectations from investors

 How much you should expect from investors depends on several key factors, including: 1. Stage of Your Startup Stage Typical Investment Range Investor Type Idea/Pre-seed $10K – $200K Friends & Family, Angel Investors Seed $250K – $2M Angel Investors, Seed Funds Series A $2M – $15M Venture Capital (VC) Firms Series B+ $10M+ Larger VC Firms, Private Equity 2. What You're Offering in Return Most investors expect equity (ownership). At early stages, typical equity offered is 10%–25% . Higher the risk, higher the expected ownership or return. 3. Your Valuation For example: If your startup is valued at $1M (pre-money) and you’re offering 20% equity, then: You can raise ~$250K (post-money $1.25M) . Valuation is often determined by: Market size Traction (users, revenue) Team quality Product readiness Competitive advantage 4. Your Needs & Milestones Base your ask on: Runway: How many months of operations the money will suppor...
