Why You Care The system needs software to meet objectives Software is everywhere in your system Lifecycle costs are a big deal Software will be continuously engineered, developed, integrated, tested, and deployed for a very long time You need to comply with cyber requirements Software is eating the world Marc Andreessen, WSJ, 2011 The Software Dilemma 2019 Carnegie Mellon University [DISTRIBUTION STATEMENT A] Approved for public release and unlimited distribution. 3 Picture (Optional)

2019 Carnegie Mellon University [DISTRIBUTION STATEMENT A] Approved for public release and unlimited distribution. 5 Picture (Optional) Data Processing Software What we are talking about: Software that connects the system to the outside world Software that plans and directs system operation Software that processes business/mission data This software uses commodity processing hardware and infrastructure that change frequently The Software Dilemma 2019 Carnegie Mellon University

[DISTRIBUTION STATEMENT A] Approved for public release and unlimited distribution. 6 Picture (Optional) Embedded Software What we are talking about: The software that controls the behavior of or processes data from the system hardware, especially unique elements in weapon systems that also need to address anti-tamper requirements - Performance critical - Mission critical - Safety critical Software development is closely tied to the hardware component development Required for proof of concept

The Software Dilemma 2019 Carnegie Mellon University [DISTRIBUTION STATEMENT A] Approved for public release and unlimited distribution. 7 Picture (Optional) Test and Development Software What we are talking about: Automated tools that support the software development pipeline Software that systematically looks for common coding errors Software that systematically measures software performance Tools are closely linked to the developers culture and processes but will be needed for sustainment of the software What types of software are in your system?

Picture (Optional) System Hardware Development Lifecycle What we are talking about: Hardware that has to be developed for your system - Vehicles: ship, air frame, rocket body - Components: engines, sensors Lifecycle patterns: Milestone decision points A. B. C. D. System meets requirements for reasonable cost and risk System design meets requirements at reasonable cost and risk System built is suitable for production in large numbers System is ready for operational deployment

Waterfall development works - Requirements, design, build, integrate, test, deploy The Software Dilemma 2019 Carnegie Mellon University [DISTRIBUTION STATEMENT A] Approved for public release and unlimited distribution. 10 Picture (Optional) Processing Hardware Lifecycle What we are talking about: Processors that will operate, test, and maintain your system - On-board processors - Mission support processors - Cloud

The software infrastructure: operating systems, database and network services Lifecycle patterns: Decision points - Form, fit, and function defined at system PDR/CDR - Buy decision delayed until as late as possible to maximize value COTS process works best - Buy the highest performing processor available - Select a compatible software infrastructure stack with processor The Software Dilemma 2019 Carnegie Mellon University [DISTRIBUTION STATEMENT A] Approved for public release and unlimited distribution. 11 Picture (Optional) Software Lifecycle

What we are talking about: Software that has to be developed for your system Off-the-shelf software that was developed for someone else Lifecycle patterns: Decision points - Similar to system hardware, but they dont line up! Incremental development works best - Concurrent requirements, design, build, integrate, test, deploy The Software Dilemma 2019 Carnegie Mellon University [DISTRIBUTION STATEMENT A] Approved for public release and unlimited distribution. 12 Picture (Optional)

Picture (Optional) Acquisition Strategy Considerations Where is the software in your system? What types? Who are your stakeholder organizations, and how will they flow down dependent requirements? Who has the authority to halt progress, and what value do they add? Does the PMO have the necessary software expertise? Do you need to contract for software expertise? Do the potential offerors have the necessary software expertise? How will they execute the systems different software domains? What visibility will the PMO have into software development? How will the software be sustained for the next 50 years? Plan for continuous engineering, development, and deployment The Software Dilemma 2019 Carnegie Mellon University [DISTRIBUTION STATEMENT A] Approved for public release and unlimited

distribution. 15 Picture (Optional) RFP Considerations PWS Are tasks outcome based? - For example, delivery of a minimally viable product in 6 months with new features every 30 days thereafter QASP How will performance be measured? Has legacy performance been benchmarked? CDRLs Do you have all/only the data you need? Do you have a plan for review of the data? How will you verify the data deliveries?

The Software Dilemma 2019 Carnegie Mellon University [DISTRIBUTION STATEMENT A] Approved for public release and unlimited distribution. 16 Picture (Optional) Source Selection Considerations Have the offeror write a story about how software will function in the operational environment (understanding of need) how offeror will interact with the PMO in managing this contract how offeror will interact with other stakeholders to validate software changes how offeror will build, test, and deploy the software in the program how the software will be sustained for the next 50 years How will you know the offeror is competent? How will you distinguish between two competent offerors?

With the subcontractors? What metrics will the contractor use to track software development progress? What metrics will the contractor use to track software system performance? Work out how the PMO will participate in design trades The Software Dilemma 2019 Carnegie Mellon University

Software-controlled everything has added a new level of complexity to system acquisition without taking any of the old challenges away One size does NOT fit all and your system may have many types of software We no longer have a software crisis, we have an ongoing dilemma Beware of silver bullets!
