Disbenefits are changes to on-going operating costs as a result of a project; they could be perceived as positive or negative. These disbenefits are included in defining the Total Cost of Ownership rather than a component of project cost, and is more of a focus for controllers due to its on-going nature rather than one time project savings and revenue.

Trying to secure a business analyst job interview in an area in which you don’t have prior experience can be a huge challenge. It’s common for recruiters and hiring managers to screen out applicants--no matter how accomplished they seem to be from their resumes--simply because the candidate’s job history doesn’t include work in the target industry...  But how do you get your foot in the door when so many recruiters and hiring managers tend to ignore applications from a candidate whose background doesn’t match the role they are trying to fill?

When security requirements are considered at all during the system life cycle, they tend to be general lists of security features such as password protection, firewalls, virus detection tools, and the like. These are, in fact, not security requirements at all but rather implementation mechanisms that are intended to satisfy unstated requirements, such as authenticated access. As a result, security requirements that are specific to the system and that provide for protection of essential services and assets are often neglected. In addition, the attacker perspective is not considered, with the result that security requirements, when they exist, are likely to be incomplete. We believe that a systematic approach to security requirements engineering will help to avoid the problem of generic lists of features and to take into account the attacker perspective. Several approaches to security requirements engineering are described here and references are provided for additional material that can help you ensure that your products effectively meet security requirements.

The point is, no amount of elegant programming can solve a system problem without someone who understands the overall system architecture, someone who understands how the business works. Attacking systems development without such orchestration, such as one program at a time, will not produce the desired results. That would be like trying to build a bridge without a set of blueprints; it would probably be disjointed and one end would likely not connect with the other in the middle.
