A method for managing permissions, using a first computing system, wherein the method comprises: identifying one or more roles available to be associated, using a reference architecture pattern, with an individual or entity taking part in the development, and/or deployment, and/or operation of two or more computing system applications; generating role data representing the identified roles; identifying a plurality of reference tiers used to create, and/or deploy, and/or operate a computing system application using the reference architecture pattern, wherein the identified reference tiers include at least a development tier and a production tier; generating reference tier data representing the identified reference tiers; for each role represented by the role data, associating at least one permission with each reference tier represented in the reference tier data; assigning, to an individual or entity of the first computing system, at least one of the roles represented by the role data; receiving a task request associated with the individual or entity, the task request including a request to perform a computing task; determining a risk level associated with a potential performance of the requested computing task, the determined risk level being at least partly based on operating characteristics associated with the requested computing task; adjusting a baseline permission associated with the requested computing task based on the determined risk level; determining whether the individual or entity is associated, through a role assigned to the individual or entity, with a permission meeting or exceeding the adjusted baseline permission; performing, if the individual or entity is associated, through a role assigned to the individual or entity, with the permission meeting or exceeding the adjusted baseline permission, the requested computing task in accordance with the request; denying the request, if the individual or entity is not associated, through a role assigned to the individual or entity, with the permission meeting or exceeding the adjusted baseline permission. identifying one or more roles available to be associated, using a reference architecture pattern, with an individual or entity taking part in the development, and/or deployment, and/or operation of two or more computing system applications; generating role data representing the identified roles; identifying a plurality of reference tiers used to create, and/or deploy, and/or operate a computing system application using the reference architecture pattern, wherein the identified reference tiers include at least a development tier and a production tier; generating reference tier data representing the identified reference tiers; for each role represented by the role data, associating at least one permission with each reference tier represented in the reference tier data; assigning, to an individual or entity of the first computing system, at least one of the roles represented by the role data; receiving a task request associated with the individual or entity, the task request including a request to perform a computing task; determining a risk level associated with a potential performance of the requested computing task, the determined risk level being at least partly based on operating characteristics associated with the requested computing task; adjusting a baseline permission associated with the requested computing task based on the determined risk level; determining whether the individual or entity is associated, through a role assigned to the individual or entity, with a permission meeting or exceeding the adjusted baseline permission; performing, if the individual or entity is associated, through a role assigned to the individual or entity, with the permission meeting or exceeding the adjusted baseline permission, the requested computing task in accordance with the request; denying the request, if the individual or entity is not associated, through a role assigned to the individual or entity, with the permission meeting or exceeding the adjusted baseline permission.
