Allovance Method
The Allovance Method is a business application that guides businesses and organizations in their decision making process. It is used to help you decide and justify how you allocate resources (capital, time, people) by taking you through 5 steps:
1. Strategize - Decide what priorities are important to you and what objectives you want to accomplish
2. Compare - Use pair-wise comparison to weigh the importance of your priorities and objectives to each other
3. Quantify - Create the scales that define the impact of each project on your objectives
4. Score - Create and score your "projects" according to the scales you defined in step 3. An overall project score is calculated for each project.
5. Select - Use data and scores to select a portfolio of projects that maximizes project scores while staying within your budget
