1. The following guidelines will help you estimate how much time it will take experienced or inexperienced personnel to develop various types of products during an interactive multimedia design project.

2. Estimates are provided for the following types of products:
   1. Reading Materials
   2. Audio and Video Scripts
   3. CBT or IMM
   4. Instructor Materials
   5. Lesson Plans
   6. Overhead Transparencies
   7. Exercises
   8. Test Items

This is a relatively crude worksheet for estimating project scope. It can be used as a guide for setting up an estimated budget for your project using a spreadsheet program.

1. Estimate the number of pages of reading materials.
   Multiply at the rate of 1 hour of time per page for experienced instructional designer.
   Increase estimate by 50% for inexperience.
   Example: 15 pages of reading materials = 15 hours for experienced; 22.5 hours for inexperienced.

2. Estimate minutes of video script.
   Multiple at the rate of 3 hours per minute for experienced script writer.
   Increase estimate by 50% for inexperience.
   Example: 10 min. of video script = 30 hours for experienced; 45 hours for inexperienced.

3. Estimate minutes of CBT or IMM.
   Multiply at the rate of 2.5 hours per minute.
   Total time for experienced instructional designer.
   Increase estimate by 50% for inexperience.
   Example: 30 min. of CBT or IMM = 75 hours for experienced; 112.5 for inexperienced.

4. Estimate the number of pages of instructor material.
   Multiply at the rate of 1 hour of time per page.
   Total time for experienced instructional designer.
   Increase estimate by 50% for inexperience.
   Example: 10 pages = 10 hours for experienced; 15 hours for inexperienced.

5. Estimate the number of lesson plans (1 per hour).
   Multiple at the rate of 10 hours per plan.
   Total time for experienced instructional designer.
   Increase estimate by 50% for inexperience.
   Example: 2 plans = 20 hours for experienced; 30 hours for inexperienced.

6. Estimate the number of transparencies.
   Multiple at the rate of .5 hour per transparency.
   Total time for experienced instructional designer.
   Increase estimate by 50% for inexperience.
   Example: 20 transparencies = 10 hours for experienced; 15 for inexperienced.

7. Estimate the number of exercises.
   Multiply at the rate of 5 hours per exercise.
   Total time for experienced instructional designer.
   Increase estimate by 50% for inexperience.
   Example: 3 exercises = 15 hours for experienced; 22.5 hours for inexperienced.

8. Estimate the number of test items.
   Multiply at the rate of .5 hour per test item.
   Total time for experienced instructional designer.
   Increase estimate by 50% for inexperience.
   Example: 50 test items = 25 hours for experienced; 37.5 hours for inexperienced.
