Controlling Cost in Complex Systems Development | 2013
Tim Bowe, Amit Shah, Chris Miles

A key goal of an effective product development process is to reduce and manage risk. Understanding the source of these risks is fundamental to developing strategies to mitigate them. A comprehensive mitigation strategy for complex systems must include the use of sophisticated simulation tools to provide an effective testing base throughout the development process and beyond. Use of simulators has shown to not only improve the overall quality of the delivered product, but also reduce both the development time and associated product lifecycle costs. This paper focuses on the benefits to be gained by using simulators in the development and testing of complex systems, along with an ROI model. 

Transitioning to RTCA DO-178C/DO-278A: A Business Manager Brief | 2012 
Hoyt Lougee

With the release of the new development guidance for certifiable aviation software, RTCA DO 178C/DO-278A, executives and business managers for manufacturers of both airborne and ground-based systems are examining the short- and long-term impacts on their certifiable-product development approaches with respect to cost, schedule, and risk. This white paper provides business management visibility into the emerging challenges and opportunities associated with the updated guidance.

Getting Ahead of the Curve: Preparation for UAS Entry into the National Airspace | 2012
Hoyt Lougee, Dave Mackersie

September 2015. This is the deadline for the FAA to fully integrate unmanned-aircraft systems (UASs)—including those intended for commercial use—into the National Airspace System (NAS). Early accommodation of the emerging FAA UAS guidance can allow manufacturers to minimize cost and schedule necessary to develop within an FAA-regulated domain. In this paper, we provide recommendations on short- and medium-term low-cost, low-impact activities to better position UAS manufacturers for a timely adoption of the FAA UAS guidance.

DO-178: It's Not the Development Burden You Might Think (PoV) | 2012
Jonathan Gray, David Martin

Developing complex software-intensive products compliant with the DO-178 standard requires very precise development and verification tasks. Many companies are challenged with how to optimize the development and verification processes required by these guidelines while effectively managing costs and productivity. This paper sets out to explain three of the most common approaches companies are using today to tackle their DO-178 development efforts. Weigh the benefits against the pitfalls of each approach while contemplating your core competencies to determine the right approach for your organization.

Technical Debt in the Aerospace Industry—It's Time to Pay it Down | 2011
Dan O'Connor, Hoyt Lougee

As the Aerospace market begins to recover and customers begin to order new products, competitiveness and time-to-market will be absolutely critical. Finding out too late about debilitating "technical debt" can derail your product development programs, resulting in costly missed market opportunities. This paper provides a quick introduction to the technical debt metaphor as it applies to best practices in software development. These concepts are then applied to the particular complexities in developing Aerospace products. Specific guidelines are provided on how to assess your legacy product software for technical debt, as you prepare to participate in the anticipated upturn.

Robust Requirements Analysis: The Key to Lower-Cost DO-178B Certified Software | 2011
Hoyt Lougee

The unpredictable cost of DO-178B certifiable software has plagued avionics manufacturers for over a decade. The requirements analysis process is often the culprit behind blown budgets, seemingly endless schedule extensions, and software project turmoil. Addressing requirements properly can provide avionics manufacturers a clear path to a predictable software certification effort, ultimately safeguarding their schedule commitments and budgets. This paper will describe common pitfalls associated with DO-178B requirements—and detail the best practices necessary to avoid them.

Architecture in an Agile World | 2011 
Dan O'Connor

Efficient agile development teams can improve an organization's responsiveness and help control engineering costs. Misaligned software architectures, however, can detract from these benefits, and agile refactoring does not scale to achieve a major architectural reset. Foliage promotes "architecture strategy" as a lightweight approach that is complimentary to agile development and will steer your product development in the right direction.

System-of-Systems Development: Competitive Advances in System Engineering | 2010 
Hoyt Lougee, Garrett Thurston

System of Systems (SoS) development is prevalent in the Aerospace domain ranging from the highest level— the global air management system, which is comprised of tightly federated agreements among countries—to individual aircraft subsystems. This paper explores the dynamics of system engineering in the development of increasingly complex products, formally introducing SoS and describing the roles of both the traditional system engineer and the SoS engineer. Within the Aerospace domain, it will describe a gradual evolution from custom-developed building blocks to flexible off- the-shelf and customized product-line subsystem offerings.

The World-Class Software Development Organization for DO-178B Certifiable Software | 2009 
Hoyt Lougee

The pursuit of a world-class certifiable-software development organization is an ever-changing dynamic process, constantly shifting to align to current and future business realities. Productivity, Predictability, and Business Alignment are the fundamental goals; the Right People, the Right Process, and the Right Tools are the solutions. In this paper, we discuss a variety of benchmarks commonly associated with world-class software development, as well as provide some insight based on Foliage's certifiable-software development experience.

Where are the Unmanned Aircraft Systems? | 2009
Hoyt Lougee

Unmanned aircraft systems (UASs) have been around since World War I, but only relatively recently is the UAS marketplace beginning to grow by leaps and bounds. To benefit from the extensive UAS capabilities and to provide a much needed economic boost to the Aviation Industry, this paper discusses how an incremental, stratified approach to UAS integration into the National Airspace System will provide US Industry the ability to compete in the global UAS market.
