CREATING SOFTWARE

Writing Software !Spending Money

Minimize Software Subject to User Experience

Corollary: If the software is really needed for any kind of scale,its probably worth doing well

(since most cost accrues over the long run)

1. Make sure youve thoughtthrough your Venture Design +

your next step requires acustom application

2. Abstract your building blocksto review with a softwarearchitect/designer in your area


14/65

2015 COWAN+

B: REVIEW YOUR BUILDING BLOCKS HOLISTICALLY

Can I use something off-the-shelf (vs. build from scratch)?

How widely is the block module used by the talent I want to

work with?

- comparative searches on job sites

-general prevalence of posts via Google, etc.

Where is it headed? Who supports it and why?

How well is that aligned with my direction?


15/65

2015 COWAN+

C: GET THE RIGHT ADVICE & DECIDE

Work with your team & contacts to seek out advice &

perspective, even if its outside.

Making the right decisions about building blocks up front can

deliver geometric returns on the value of the time invested.
