Bryan Chapman has extracted the following ratios of time to create learning from several Brandon Hall Research reports. The ratio is production hours (including analysis, design, and development) versus 1 hour of "seat time".
- 34:1 (ILT) = 5 days
- 33:1 (PowerPoint to e-learning) = 5 days
- 220:1 (Standard e-learning) = 1.5 months
- 345:1 (3rd party) = 3.5 months
- 750:1 (Interactive simulations) = 5 months
Clark Aldrich has looked at the cost that organisations have to spend to access an educational simulation, either by commissioning custom simulations or licensing them "off-the-shelf, per named user."
| Custom (S) | Custom (M) | Custom (L) | Library (S) | Library (M) | Library (L) | |
| Branching | 30K <10m | 100K 10-30m | 500K 30m-2hr | $30 | £100 | $500 |
| Mini Game | 10K 5m | 15K 10m | 40K 30m | n/a | n/a | n/a |
| Virtual Product | 30K 30m | 75k 1hr | 150K 4hr | $10 | $30 | $100 |
| 3D | 100K+ 1hr | 500K+ 5hr | 1000K+ 20hr | $100 | $400 | $1000 |
Other items that typically increase costs include:
- Full motion video (use comics/illustrations instead)
- Advanced graphics
- Customising software instead of using off-the-shelf
- Building a complex game
