System software is used to run computer hardware and provide basic services to the applications that run on top of it. Operating system software is an example of system software. System software is typically written in a low-level computer language to maximize speed and efficiency.
Application software provides functionality to users. Enterprise software, personal software, and mobile apps are all examples of application software. Application software may be written in high-level languages, generated from design models or assembled from pre-built components.
Embedded software is special-purpose software that monitors and controls microprocessors used in airplanes, automobiles, thermostats, and other physical products. Embedded software is often packaged in electronic control units (ECUs) to deliver sets of functionality. For example, different ECUs provide automotive braking, navigation, safety, and other capabilities. Embedded software typically requires a real-time response, mandating a Real-Time Operating System (RTOS) and programming language.
Agility - Respond rapidly to evolving customer and market needs. Agile practices optimize agility through short sprints and frequent deliveries.
Analytics - Capture and analyze team metrics that align activities with the highest priorities and establish a foundation for continuous improvement.
Change Management - Manage changes to requirements, code, and test assets to rapidly cascade changes through the team. Branch and merge assets to easily create variants.
Continuous Integration and Delivery (CI/CD) - Merge code changes into a shared repository that is integrated, compiled, tested, and delivered at regular intervals, accelerating software delivery.
DevOps - Adopt automated, repeatable release management processes that accelerate the delivery of value to customers.
Security - Manage the chain of custody and authorization of strategic software assets through audit trails, e-signatures, and other governance techniques.
Requirements Management - Iteratively analyze and define the scope of a solution and develop detailed specifications.
Test and Quality Management - Validate and verify results at each stage to improve outcomes and reduce the cost of quality.
Release planning - Plan and manage the distribution of software to end users.

The open platform extends ALM workflows with powerful Agile software engineering capabilities. Codebeamer provides requirements, risk, and test management, best practice workflows, integration with your development toolchain, and support for Agile and V-model methodologies. With Codebeamer, teams can realize value from day one, tailoring the tool to their needs. Simplify regulatory compliance with pre-configured templates. Enjoy 360-degree traceability from idea to delivery. Codebeamer builds on the Open Services for Lifecycle Collaboration (OSLC) standard to integrate with the PTC engineering digital thread.
Software development techniques are always changing. In the past, programmers wrote applications from start to finish. Today, software engineers use Agile methods to quickly deliver value over short iterations. They may generate code from design models or utilize reusable, off-the-shelf components to achieve their objectives in a fraction of the time and cost. In the future, AI-assisted engineering will bring about yet another wave of software development efficiency.
Embedded software development differs from application development in many ways. Embedded software is typically:
Regulated industries, including aerospace and defense, medical and pharmaceutical, and transportation and automotive, impose specialized requirements for building safety-critical products. These requirements govern both the safety and quality of the end products, as well as the rigor of the software development process itself. In general, software development in regulated industries requires greater attention to governance, security, and auditability.
