I am working on a Software Development Plan for a new large software project to be delivered to NASA. The primary parts of the project are for man-rated, safety-critical software and must be compliant to NASA NPR 7150.2D, NASA-STD-8739.8B and CMMI-DEV Level 3. List and describe the key elements that I must specify for the Introduction, Scope and Objectives section of the SDP.

For the Introduction, Scope, and Objectives section of a Software Development Plan (SDP) tailored to a NASA project requiring compliance with NASA NPR 7150.2D, NASA-STD-8739.8B, and CMMI-DEV Level 3, you should detail specific key elements, as follows:

1. Introduction

• Project Overview: Summarize the project's high-level objectives, emphasizing that it is a man-rated, safety-critical software project and the importance of adhering to NASA and CMMI-DEV Level 3 requirements. Highlight any unique aspects or constraints, such as mission-critical timing or specific hardware dependencies.
• Compliance Requirements: List the key NASA standards (NPR 7150.2D, NASA-STD-8739.8B) and the CMMI-DEV Level 3 maturity model. State explicitly that these standards govern the development process and the final software product to meet NASA’s high reliability and safety criteria.
• Stakeholders: Identify the primary stakeholders involved, including NASA as the client, the software development team, quality assurance, and safety engineers. List relevant NASA divisions or contractors who will provide oversight or collaboration.
• Document Purpose and Audience: Explain that this SDP outlines the approach and responsibilities for the project’s development, providing guidance to project managers, engineers, quality assurance teams, and stakeholders for review and approval.

2. Scope

• Project Boundaries: Define the scope by specifying the boundaries and expected deliverables of the software product. This includes outlining the primary functionalities, critical components, interfaces, and any exclusions (e.g., non-critical ancillary functions).
• Software Safety Classification: Establish the project’s safety classification and how it aligns with man-rated, safety-critical requirements. Define safety-critical elements, such as hazard detection and fail-safe mechanisms, that will impact design decisions.
• Requirements Traceability: Reference the use of a traceability matrix or tool to track and ensure that all NPR 7150.2D and NASA-STD-8739.8B requirements are addressed and validated.
• Constraints and Assumptions: Identify any critical constraints, such as hardware compatibility, operational environments (space, lunar, Mars, etc.), timing requirements, or assumptions like third-party software integration or existing NASA systems interfacing.

3. Objectives

• Mission Objectives Alignment: Describe how the software aligns with and supports the mission objectives set by NASA. Specify how the software will contribute to mission success and safety, including risk mitigation strategies.
• Safety and Reliability Goals: Define clear goals for achieving high safety and reliability metrics, given the software’s critical nature. Explain how these goals align with NPR 7150.2D and NASA-STD-8739.8B and mention any measurable outcomes or metrics.
• Quality and Performance Objectives: Specify measurable quality objectives, such as defect density or performance under load, as well as any environmental factors (e.g., radiation tolerance). Define compliance targets aligned with CMMI-DEV Level 3, ensuring repeatable, managed processes are in place.
• Compliance and Audit Objectives: Include objectives for meeting or exceeding compliance with NASA standards, particularly NPR 7150.2D and NASA-STD-8739.8B, as well as CMMI-DEV Level 3. Describe planned audit milestones and any tools or processes used to maintain compliance throughout the project lifecycle.

Each of these sections should clearly articulate how the SDP will guide the project toward delivering a compliant, safe, and reliable product that meets NASA's mission-critical requirements and development standards.

Based on the question-and-answer worksheet you provided, here’s a structured draft for the Introduction, Scope, and Objectives section of your Software Development Plan (SDP):

1. Introduction

The purpose of this software development project is to create man-rated flight software for controlling a spacecraft designed to transport astronauts from Earth to the International Space Station (ISS), dock, and safely return to Earth. Given the mission's safety-critical nature, the software development process will prioritize safety in every aspect.

This software is classified as man-rated and safety-critical because it will manage functions directly impacting the safety and lives of astronauts onboard the spacecraft. Any failure in functionality could endanger the crew, making adherence to rigorous safety standards essential.

The project is governed by NASA standards NPR 7150.2D (Software Engineering Requirements), NASA-STD-8739.8B (Software Assurance and Software Safety Standards), CMMI-DEV Level 3 (Capability Maturity Model Integration for Development), and AS 9100 (Quality Management Systems - Requirements for Aviation, Space, and Defense Organizations), along with applicable agency and federal security requirements. Compliance with these standards ensures that the development processes, quality assurance, and safety protocols align with NASA's stringent requirements for man-rated software.

Primary stakeholders in this project include NASA astronauts, NASA Engineering, NASA Operations, and NASA Safety and Mission Assurance teams. These stakeholders provide oversight, guidance, and support to ensure that the software aligns with mission requirements and safety objectives.

This Software Development Plan (SDP) is intended for both company and NASA management. It serves as a guiding document that supports the creation of lower-level documentation necessary for the software development team to execute the project in compliance with NASA standards and objectives.

2. Scope

The project’s scope includes software functionalities that support ground operations, launch and landing teams, and primarily spacecraft avionics and system management. These functionalities are essential for the safe launch, in-orbit operations, docking, and return of the spacecraft.

This software is classified as NASA Class A software, with some supporting elements possibly classified as NASA Class C. Under NASA’s criteria, all Class A software is considered safety-critical due to its direct impact on mission and crew safety, requiring stringent design and testing protocols.

To ensure all NASA requirements are met, particularly those specified in NPR 7150.2D and NASA-STD-8739.8B, the project will be certified at CMMI-DEV Level 3. Internal audits will be conducted to validate compliance, and the software team will support any audits directed by NASA. Additionally, a traceability matrix or tool will be used to track each requirement from conception to verification, ensuring no requirements are overlooked.

The development process will consider key constraints and assumptions, including hardware compatibility, operational environments, timing requirements, and integration with other NASA systems. The software developed by this team will be jointly tested with systems on the NASA ISS and other provider spacecraft, ensuring interoperability and reliability.

3. Objectives

The primary objective of this project is to align with and support NASA’s mission objectives by controlling all critical functions for the safe launch, docking, and return of a manned spacecraft to and from the ISS.

Safety and reliability goals are paramount. This project will meet all safety requirements and standards outlined in the contract, statement of work (SOW), NPR 7150.2D, and NASA-STD-8739.8B. Compliance with these standards is necessary to meet the safety-critical classification of Class A software.

While specific quality and performance objectives (such as defect density and performance under load) are not defined at this stage, they will be established as the project progresses and as more system requirements are finalized.

Compliance with NASA standards (NPR 7150.2D, NASA-STD-8739.8B) and CMMI-DEV Level 3 requirements will be ensured through internal quality assurance audits. NASA-led audits will also be supported to verify that the software development team meets all compliance criteria.

Audit milestones, tools, and processes to maintain compliance throughout the project lifecycle have yet to be defined and will be specified as the project moves into later stages of development.

This structured draft will help you populate the necessary details in your Software Development Plan’s Introduction, Scope, and Objectives section, aligning the project’s goals with NASA’s stringent standards for safety-critical software development.
