"planificacion estrategias" » "planificacion estrategica", "aplicacion estrategias", "comunicacion estrategias", "planificacion estrategicas", "justificacion estrategicas", "plantacion estrategicas"
"planificacion estrategia" » "planificacion estrategica", "justificacion estrategica", "plantacion estrategica"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("planificacion estrategias") OR ("planeacion estrategica"))) or ((("gamification strategys") or ("gamificacion estrategia"))))) or ("planificacion estrategia"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("planificacion estrategias") OR ("planeacion estrategica"))) OR ((("gamification strategys") OR ("gamificacion estrategia"))))) OR ("planificacion estrategia")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"planificacion estrategias\") OR (\"planeacion estrategica\"))) or (((\"gamification strategys\") or (\"gamificacion estrategia\"))))) or (\"planificacion estrategia\"))".
• Removing quotes may allow a broader search: (((((( planificacion estrategias ) OR ( planeacion estrategica ))) or ((( gamification strategys ) or ( gamificacion estrategia ))))) or ( planificacion estrategia )).
• Adding a wildcard symbol may retrieve word variants: (((((("planificacion estrategias") OR ("planeacion estrategica"))) or ((("gamification strategys") or ("gamificacion estrategia"))))) or ("planificacion estrategia"))*.
