    1. 1. Decision Matrixes<br />@wickedgeekie - 2010<br />
    2. 2. A series of solutions has been identified, how can I find out which one fits best the project requirements? How can I justify this selection? How can I conduct this selection with many people?<br />
    3. 3. Welcome to decision matrixes. This is an example matrix. Does this look familiar?<br />
    4. 4. What is a decision matrix?<br />A decision making technique<br />which enables to<br />catalogue options<br />identify options’ strengths and weaknesses<br />rank options against project requirements<br />identify the option fitting most closely project requirements<br />documents decisions for future reference<br />conduct all of the above with 1 or more people<br />

    6. 6. Decision matrixes can be as complex as one wants them to be...<br />
    7. 7. Walk-through example<br />Fanta want to promote their new product on Facebook by enabling users to download a voucher.<br />Which Facebook product is best suited for this?<br />
    8. 8. Designing the matrix:Inserting the criteria<br />Listing the decision criteria<br />The page features a voucher, or a link to one<br />The brand remains in control of user generated contentof the page<br />The page must be highly visible to generate a high volume of downloads<br />The solution must be scalable for future promotions<br />
    9. 9. Designing the matrix: Adding the propositions<br />Listing the propositions<br />A list of possible formats of page has been drawn, and form the propositions:<br />A Group page<br />A Product or Fan page<br />An Event page<br />An Application<br />
    10. 10. Filling in the matrix: comments<br />Scoring the propositions for one criteria is much easier as the understanding of what the criteria is is consistent<br />
    11. 11. Adding a ranking scale: 1- lowest desirability to 5 – highest desirability<br />3<br />5<br />2<br />5<br />3<br />1<br />2<br />5<br />2<br />4<br />3<br />1<br />4<br />5<br />4<br />5<br />
    12. 12. Keeping only ranking scores<br />3<br />5<br />2<br />5<br />3<br />1<br />5<br />2<br />2<br />4<br />3<br />1<br />4<br />5<br />4<br />5<br />
    13. 13. Check if the scores are spread enough: this validates the criteria<br />3<br />5<br />2<br />5<br />3<br />1<br />5<br />2<br />2<br />4<br />3<br />1<br />4<br />5<br />4<br />5<br />1<br />4<br />2<br />1<br />These criteria get scores that are too clustered, they may not be valid – or use weighing to differentiate them<br />
    14. 14. Adding weighing<br />3x3= 9<br />5x2= 10<br />2<br />5<br />3x3= 9<br />1x2= 1<br />5<br />2<br />2<br />4<br />3x3= 9<br />1x2= 1<br />4x3= 12<br />5x2= 10<br />4<br />5<br />Not all criteria are equal, add weighing to distinguish most/least important<br />
    15. 15. Calculating totals<br />3x3= 9<br />5x2= 10<br />2<br />5<br />26<br />3x3= 9<br />1x2= 1<br />5<br />17<br />2<br />2<br />4<br />3x3= 9<br />1x2= 1<br />16<br />4x3= 12<br />5x2= 10<br />4<br />5<br />31<br />The last result has the highest total, it matches best the criteria selected.<br />
    16. 16. Calculating totals<br />3<br />5<br />2<br />5<br />15<br />3<br />1<br />5<br />11<br />2<br />2<br />4<br />3<br />1<br />9<br />4<br />5<br />4<br />5<br />18<br />Criteria can be added or removed, the results are easy to update<br />Helps manage scope creep<br />All stakeholders can contribute<br />Great for sorting findings of a mind map<br />
    17. 17. In the UX work process...<br />Can help clarify requirements across the team<br />Documents why a solution is selected<br />Can be conducted with or without the client, depending on timing/internal consensus<br />Can be a deliverable if the question is: “what solution is best and why?”<br />Stakeholders may need to be explained what it is and why it’s useful<br />
