Study Notes

Software Products

  • Software products are generic systems offering functionalities useful to various customers.
  • Examples range from large-scale business systems (e.g., MS Excel) to personal software (e.g., Evernote), simple mobile apps, and games (e.g., Sudoku).
  • Software product engineering evolved from methods supporting one-off custom software.
  • Custom software remains essential for large businesses and public bodies, developed through dedicated projects.

Project-Based Software Engineering

  • Starts with a set of software requirements outlined by an external client, defining the system's tasks.
  • A software company (contractor) develops the system per these requirements.
  • Clientele frequently change requirements in response to business changes.
  • Contractors must adapt the software to reflect these adjustments.
  • Custom software projects typically have extended lifecycles (10+ years) requiring ongoing support.

Product Software Engineering

  • Starts with a recognized business opportunity.
  • A company creates a software product to leverage this opportunity for customer sale.
  • The software company designs and develops features.
  • The software development company decides the project timeline, what features to include, and when changes are needed.
  • Rapid product delivery is critical for market capture.

Software Product Lines and Platforms

  • A product line comprises software products sharing core functionality.
  • Each product in a line has customer-specific additions and adaptations.
  • Software product lines facilitate fulfilling custom needs not met by a generic product.
  • A platform is a software (sometimes combined with hardware) product enabling new applications' creation.
  • Real-world examples include Facebook, offering extensive functionality and support for creating apps.

Software Execution Models

  • Stand-alone execution: software runs on the user's computer, with all functionality and data residing there.
  • Hybrid execution: a blend of stand-alone and service-based execution, with some functions and parts of the data stored on the user's computer and others on the vendor's server.
  • Software as a service: software functionality runs on the vendor's servers, with users accessing it through a user interface. Data is managed on vendor servers; updates and changes are managed by the vendor,

Comparable Software Development

  • Product development lacks an external customer providing requirements.
  • This characteristic also applies to student projects (for a course), research software (analyzing research questions), and internal tools (for company use).

Software Product Management

  • It is a business activity focused on software products developed and sold by a business.
  • Product managers (PMs) control overall responsibility.
  • This role incorporates planning, development, and product marketing.
  • PMs serve as the interface between the business, customers, and the development team.
  • PMs manage the product lifecycle from inception to withdrawal from the market, ensuring alignment with business goals and customer needs.

Product Management Concerns

  • PMs ensure products align with business goals.
  • Effective communication of technology concerns to the development team.
  • Sustaining regular communication with customers and prospective customers to understand their needs and requirements.

Technical Interactions of Product Managers

  • Product vision management: establishing and maintaining consistency in the product's vision.
  • Product roadmap development: defines the development, release, and marketing strategies.
  • User story and scenario development: PMs define how customers interact with the product.
  • Product backlog creation and management: prioritize tasks for software development.
  • Acceptance testing: verifies software aligns with goals and functionality.
  • Customer testing: gathers feedback on product operation and usability.

Product Prototyping

  • Product prototyping: creating an initial version to test ideas and secure funding.
  • Essential for visually demonstrating product functionalities for potential customers.
  • Two-stage prototyping (feasibility, customer demonstration) allows a structured approach.

Key Points 1 and 2

  • Software products comprise widely applicable functionalities.
  • In product engineering: the same organization handles product feature definition and development.
  • Software products may exist as stand-alone, hybrid, or service-based systems.
  • Key product management responsibilities include product vision, roadmap, user stories, backlog, and testing; PMs facilitate communication amongst stakeholders.
