DARPA innovation model reveals efficiency: 124 staff drive breakthroughs with 5-10% success rate, $12m avg program budget. 4-5yr PM tenure, 3 management layers, 0.5% of DOD spend.
Read this over the weekend on how DARPA works, some neat factoids and a great quote from former director on being constrained by ideas. For a risk seeking organization surprising high success rate btw 5-10%, and only 10% of program are killed early.
"...DARPA is relatively tiny and flat. As of April 2020,DARPA has 124 staff and three layers of management. That number is right around Dunbar’s Number - just small enough for one person to know everyone in the organization. The small organization means that there are no “group projects” so every PM is directly responsible for the program they’re working on and you can’t have slackers. Small size also helps keep PM quality high by removing pressure to hire a lot of people.... DARPA Program managers have a tenure of four to five years. This transience is important for many reasons. Transience can inculcate PMs against the temptation to play it safe or play power games because there’s only one clear objective - make the program work. You’re out regardless of success or failure..... Only 5-10 out of every 100 programs successfully produce transformative research, while only 10% of projects are terminated early. Shifting the risk from the performers to the program managers enables DARPA to tackle systemic problems where other models cannot.... DARPA is ~0.5% of the Department of Defense Budget and ~12% of that is basic research…. at its height, Bell Labs’ budget was only 5% of AT&T’s revenue…A lot of DARPA’s budget is spent on actually assembling weapons and vehicle systems. So the math works out that only ~$400m is actually being spent on ‘basic research.’ … in the years 2018-2020among DARPA programs not focused on assembly and production the minimum budget was $2m, the maximum budget was $31.4m, and the average budget was $12m. …These raw numbers raise the question - is there a ‘minimum effective budget’ to generate outlier results? If so, what is it? DARPA is more ideas limited than money limited. This excerpt is gold: “I never really felt constrained by money,” (former DARPA director) Tether says. “I was more constrained by ideas.”…”

The vc giants’ newfound contrition comes on the back of a gigantic tech crash. The tech-heavy nasdaq index fell by a third in 2022, making it one of the worst years on record and drawing comparisons with the dotcom bust of 2000-01. According to the Silicon Valley Bank, a tech-focused lender, between the fourth quarters of 2021 and 2022, the average value of recently listed tech stocks in America dropped by 63%. And the plunging public valuations dragged down private ones (see chart 1). The value of older, larger private firms (“late-stage” in the lingo) fell by 56% after funds marked down their assets or the firms raised new capital at lower valuations.
