Making a Proposal for Digital Prototyping in 7 Steps

At the moment using digital prototypes can complement and, in some instances, even exchange using bodily prototypes. Digital prototypes assist cut back the dangers, prices, and time for creating modern new merchandise. Design engineers can assemble and retailer hundreds and even tens of millions of 3-D digital prototypes of a possible product in a design choice tradespace. The efficiency and conduct of every digital prototype will be assessed shortly utilizing simplified physics-based software program. Extra subtle high-fidelity computational evaluation instruments can then be used to precisely predict the efficiency of essentially the most promising candidates—all this earlier than a bodily prototype exists. Lastly, if wanted, a bodily prototype of the ultimate design will be constructed and examined for remaining validation of the design earlier than manufacture. Digital prototypes assist cut back the price of scientific analysis and tackle analysis issues that can’t be addressed through experiments.

The primary enablers for digital prototyping are software program functions and high-performance computer systems. Excessive efficiency computer systems are a commodity, however the wanted software program shouldn’t be. In lots of instances the mandatory software program have to be developed to satisfy the wants of digital prototyping. Growing efficient software program engineering practices for digital prototyping and different kinds of software program are necessary analysis matters for the SEI.

Regardless of its promise, digital prototyping presents a severe problem: engineers and scientists usually have no idea learn how to create a compelling proposal for a digital prototyping program—particularly the important thing software program element—and get it in entrance of the correct set of eyes to acquire funding and help.

This weblog publish, which is excerpted and tailored from Creating and Utilizing Digital Prototyping Software program, a e-book that I coauthored with Dr. Richard Kendall, outlines seven steps to create a compelling proposal for potential sponsors to help a program to develop, deploy, and maintain suites of digital prototyping instruments. The suggestions within the e-book are primarily based on our expertise during the last 17 years establishing and sustaining the Division of Protection (DoD) digital prototyping program CREATE (Computational Analysis and Engineering Acquisition Instruments and Environments). Launched in 2006, the CREATE program permits DoD engineers and scientists to assemble digital prototypes of main weapons techniques, reminiscent of ships, air and floor autos, and radio frequency antennas.

Through the formative stage of CREATE, its founders (together with this e-book’s authors) didn’t have a information for creating and advertising and marketing proposals for virtual-prototype device improvement. To treatment this hole, we’ve reviewed our experiences from CREATE and different advanced, science-based software program improvement applications, each profitable and unsuccessful, to determine the components that led to their success or failure and to derive a set of classes discovered. Some examples of our sources embody Software program Engineering for Science by Carver et al and the journal article “Software program Challenge Administration and High quality Engineering Practices for Advanced, Coupled MultiPhysics, Massively Parallel Computational Simulations,” which I coauthored with Dr. Richard Kendall.

We ship these insights as a set of seven steps provided as a information for related undertakings. Though these steps is perhaps thought-about apparent to anybody in Silicon Valley, we’ve discovered that the majority engineers and scientists haven’t been uncovered to them. Few have expertise with creating proposals for the development of sturdy software program that they’ll use to make the shift to digital prototyping doable.

The seven steps we advocate for producing such proposals adhere to the ideas described within the well-known Heilmeier Catechism, outlined in Determine 1 beneath. The Heilmeier Catechism was developed for assessing proposals to DARPA, and it has lengthy served as a information for producing proposals for profitable technical applications.

Determine 1: George H. Heilmeier, a former DARPA director (1975-1977), crafted a set of questions often known as the “Heilmeier Catechism” to assist company officers assume by way of and consider proposed analysis applications. Supply: https://www.darpa.mil/work-with-us/heilmeier-catechism.

Supply: Protection Advance Analysis Tasks Company

Earlier than beginning, it’s essential to evaluate whether or not switching to digital product design and testing can plausibly make a considerable enchancment in a company’s product improvement course of. It may very well be, for instance, that present pc modeling approaches are too immature to help the change, or that the computing energy wanted shouldn’t be available. Furthermore, there could also be insurmountable cultural obstacles to adoption of the paradigm.

Likewise, switching to using digital prototyping for scientific analysis ought to be achieved provided that compelling benefits will be gained over conventional scientific analysis strategies. As an example, supernova analysis carried out through experiments with high-energy-density laser amenities, such because the Nationwide Ignition Facility (NIF) on the Lawrence Livermore Nationwide Laboratory, are possible, however very costly. Pc simulations of supernova conduct that can be utilized to determine the important thing traits and physics components by evaluating the calculations with observational information are each possible and comparatively reasonably priced (Lamb 2011).

If shifting ahead is believable, then listed here are the steps.

Step 1: Develop a imaginative and prescient and determine a sponsor.

Now we have studied and adopted dozens of digital prototyping applications by way of both private participation or statement and evaluation. The applications typically begin with a small crew that develops an idea, or “imaginative and prescient,” for a way digital prototyping might enhance (i.e., make extra aggressive) a company’s product improvement or scientific analysis. In virtually all of the profitable instances we all know, the main target was on a particular use of digital prototyping, reminiscent of climate forecasting or plane design and efficiency evaluation. The crew was in a position to flip its imaginative and prescient right into a proposal {that a} sponsor then accepted and funded.

The institution of an actual program is at all times preceded by the conversion of the imaginative and prescient right into a written proposal. Preparation of the proposal typically obtained help (normally at a really modest stage) from advocates throughout the group who had been excited about exploring the idea. Generally a gaggle of passionate volunteers had been the sparkplugs who obtained issues shifting and satisfied the group’s management that digital prototyping was price exploring.

With a imaginative and prescient in hand, the main target ought to flip to figuring out potential sponsors. More often than not, the sponsor is the group’s administration crew or some a part of it. A little bit of evangelizing could also be required to get a dedication from a possible sponsor to fund the event of a proposal. Nonetheless, the assets wanted to develop a proposal are small in comparison with the potential profit. Our expertise with CREATE signifies {that a} good begin on a reputable proposal may even be developed by volunteers, working totally on their very own time.

Step 2: Do your homework.

The solutions to the next questions ought to be investigated in preparation for the proposal:

  • For product design, is the group dropping market share to an modern competitor? How can digital prototyping assist repair this?
  • Equally, can using digital prototyping enhance the standard of scientific analysis by supplementing or changing massive, costly analysis amenities?
  • What are the very best precedence wants for product design software program:
    • preliminary design?
    • efficiency prediction?
    • manufacturability?
  • What are the best obstacles that may stop potential sponsors from adopting the digital prototyping paradigm:
    • an absence of appreciation by center administration of the implications of the group’s declining competitiveness and the necessity to tackle it?
    • concern about the necessity to prepare the work pressure in digital prototyping and the potential resistance to vary?
  • What do potential sponsors must do to combine digital prototyping into their product improvement or analysis workflows to beat the obstacles?


  • What assets and modifications to the organizational tradition are required?

After finishing steps 1 and a pair of, the proposal crew ought to be educated concerning the candidate sponsor’s tradition, personnel construction, product design functionality and strategies, high quality management processes, and different attributes necessary to shifting ahead. This data will probably be necessary in the course of the improvement of a plan that features estimates for the wanted assets (price range, time, coaching, computer systems, IT help, and so forth.). Pilot tasks could also be useful, in addition to the experiences of comparable non-competing tasks, if they are often shared.

Step 3: Determine and start to recruit potential stakeholders.

It’s important that the proposal crew domesticate help inside every potential sponsor’s management crew and workers. Different stakeholders will possible profit from digital prototyping, and an effort to enlist their advocacy will be useful. Adopting digital prototyping includes a significant paradigm shift for everybody. That stage of cultural change usually (normally) encounters sturdy resistance, as Machiavelli famous in The Prince.

Our expertise signifies that adoption faces much less resistance in two instances. The primary is with sponsors which have a historical past of innovation. The second is when a company has encountered an existential risk and it’s clear that digital prototyping provides a reputable strategy to mitigate that risk. It’s arduous to overstate resistance to vary; evidently those that most want to vary are sometimes those most proof against it.

Along with funded efforts, senior folks within the discipline are sometimes keen to spend time to debate points and provide recommendation to applications that they see filling an necessary group want, as we noticed with CREATE. The proposal will possible not get far with out allies and supporters, each within the group and in associated communities. To enlist them, the proposal crew must do the next:

  1. Discover and determine stakeholders whose success will probably be enormously aided by the enhancements that digital product design and testing can provide.
  2. Have interaction their curiosity and enlist their endorsement and help.

Nonetheless, a little bit of warning is required. The most important goal of digital prototyping is to ascertain a aggressive benefit. The aggressive benefit will be misplaced if a competitor has detailed data of your program. It’s thus necessary to just be sure you solely share data with folks you belief and who shouldn’t have a battle of curiosity.

In observe, all these steps ought to be taken roughly concurrently. They are going to possible require a number of iterations and shut collaboration among the many proposal crew leaders and potential stakeholder teams. A very powerful stakeholders are the potential sponsors, however all potential stakeholders are useful; they supply gravitas.

Step 4: Consider the software program choices.

The proposal will probably be stronger if it identifies at the least a number of particular exterior examples of digital prototyping software program functions that members of the potential sponsor’s group can acknowledge and perceive. The proposal will probably be even stronger if the proposal crew can discover illustrative examples of software program functions that reveal the effectiveness of digital prototyping for the sponsor’s product improvement or scientific analysis matters. As an example, if fluid stream is necessary, an instance of using a computational fluid dynamics (CFD) code could also be acceptable. CFD is ubiquitous within the evaluation of air automobile efficiency, lowering car wind resistance, and designing quick crusing ships (such because the America’s Cup ships). These makes use of are wealthy sources of examples.

Efficiently establishing a digital prototyping functionality requires acquiring the correct software program functions, both by way of inner improvement or by exterior acquisition. The software program functions should have the capabilities and options wanted to attain a aggressive benefit.

After finishing step 4, the proposal crew ought to perceive the technical challenges concerned in creating a product or conducting scientific analysis. An exception often is the challenges particular to creating physics-based, high-performance computing software program, which can be a brand new specialised space for a lot of software program improvement teams. With the ability to overcome the challenges of creating physics-based high-performance primarily based software program is essential to the success of the proposal. If the crew doesn’t have already got that experience, it might want to purchase it to provide a reputable proposal and a profitable program.

Step 5: Assemble the proposal.

The target in step 5 is to show the imaginative and prescient of step one into a proper proposal for the software program improvement program that has a great probability of being accepted and funded. The proposal ought to have two elements. The primary half ought to

  • present a compelling description of the product improvement or analysis issues that digital prototyping will resolve
  • clarify why fixing these issues is necessary to the possible sponsor, and
  • describe the potential impression of fixing these issues

Steps 2, 3, and 4 are essential precursors right here.

The primary a part of the proposal is crucial half. It should set up the worth of digital prototyping to the success of the sponsors. If the sponsors aren’t satisfied that what’s being proposed will make them extra aggressive, the second a part of the proposal (plans and assets) will probably be irrelevant.

Proposal define.

Along with the three matters above, first half ought to embody the next:

  • an outline of the stakeholder communities (together with the sponsor)
  • a compelling and credible imaginative and prescient for a way the proposed software program functions to allow digital prototyping will probably be used
  • a plan to take care of the adoption problem—persuading the product designers or analysis scientists to maneuver from a bodily prototype or experiment-based workflow to a digital prototyping workflow
  • an outline of the required software program functions that will probably be wanted, whether or not by way of inner improvement, from exterior sources, or each
  • a reputable method and plan for a way the software program functions will be both developed or acquired from exterior sources after which deployed
  • if the software program is to be developed internally, a reputable method for recruiting and organizing the software program improvement crew that may efficiently develop and deploy the required software program
  • an outline of the organizational construction of the proposed program, together with the next:
    • names, skilled credentials, expertise, and expertise of potential program and improvement code crew leaders and crew members, if doable
    • background, expertise, and expertise of potential members of the consumer group
  • explanation why the proposed program will succeed and why the proposal is credible (Software program improvement is a dangerous enterprise.)

The second a part of the proposal ought to embody these parts:

  • an outline of the assets required for this system (funding, skilled workers, pc and pc infrastructure assets, enterprise assets, validation information, and extra)
  • a high-level conceptual improvement and deployment plan (together with a notional schedule) for the staged supply of the software program’s options
  • a short-term plan for beginning up this system in the course of the first 3 to six months if the proposal is accepted

Step 6: Market the proposal to the potential sponsors and stakeholders.

For advertising and marketing to an organization or authorities engineering group, the sponsors are the company administration, together with the engineering and monetary managers, the company advertising and marketing group, and the engineering consumer teams. For advertising and marketing to a scientific analysis group, the sponsors are the management of the establishments that execute analysis tasks and the organizations that fund or approve the establishment’s analysis program.

Advertising and marketing the primary a part of the proposal ought to tackle these areas:

  • the necessity for change
  • the imaginative and prescient for the function of digital prototyping within the path ahead
  • a plan to have interaction the stakeholder group
  • a reputable software program deployment technique (together with software program improvement or procurement)
  • Affirmation that this system management can assemble a reputable software program improvement crew and lead it to success

If the potential sponsors aren’t attracted by these matters, they won’t have an interest within the particulars of the execution plan. It’s essential that the proposed price range, schedules, and deliverables be sensible and that the proposal crew can defend the numbers. Potential sponsors will use the realism of the price range, schedule, and program targets as an necessary measure of the proposal’s credibility.

The proposal is primarily a bid to develop (or procure) and deploy software program to help the digital prototyping functionality that the sponsor wants. Right here “deploy” signifies that the software program turns into a part of the product improvement workflow. It’s also necessary to not underbid the fee and the time. If the sponsor agrees to fund the challenge, the event groups will probably be accountable to ship an inexpensive approximation of the deliberate software program on time and inside price range.

It is vital for the sponsor to grasp that the software program’s capabilities will in all probability be delivered incrementally and that it have to be supported for so long as the consumer group depends upon it. The engineering and analysis necessities will evolve and alter, and the software program might want to change to satisfy the brand new necessities. As well as, computing applied sciences (together with pc architectures and pc safety safeguards) are frequently altering, and the software program should adapt to those modifications. It’s a fallacy to assume that the software program will ever be “completed.” As quickly because the help for the software program functions ceases, it can die.

For brand spanking new groups creating software program, the funding ought to begin at about 20 % to 40 % of the deliberate asymptotic funding stage and ramp as much as it over a interval of three to five years. If the crew will probably be staffed by workers of the sponsor, build up extra quickly is perhaps doable. If present software program is being configured (versus developed) to help the digital prototyping paradigm, much less time will probably be wanted.

Step 7: Reply to proposal determination.

If the proposal is accepted, transfer ahead with planning and executing the proposed program (Chapter 7 in our e-book consists of subsequent steps). If the proposal shouldn’t be accepted, discover out why it was poor and see in case you can treatment the deficiencies. If not, do a autopsy retrospective to extract the teachings discovered and think about whether or not to strive once more with one other candidate sponsor.
