Resources | Low Resources | Moderate Resources | High Resources |
Based on the number of personnel required to execute the retirement (including any client transitions): low, moderate or high | Work can be done generally be done by an INDIVIDUAL staff member or equivalent, within the context of existing assignments and responsibilities; no separate budgeting and resource allocation is usually done for this level; time is usually measured in DAYS
| Usually confined to a single TEAM with contacts into other parts of the organization and into business stakeholder groups; formal resource allocation is often involved, and an ad-hoc team may be formed; projects in this category may involve software licenses and other materials and services budget items; time is usually measured in WEEKS
| May involve an entire ORGANIZATION of project teams, operational teams, and transition teams, staff in many parts of the organizations, consultants, formal budgets usually accounted for as part of IS&T’s central budgeting process, significant licensing, materials and services, and capital budgets; time is usually measured in MONTHS or YEARS

Impact to the MIT Community | Low Impact | Moderate Impact | High Impact |
How much of the MIT community will this effort affect and how much will they be affected? | LOW impact confined to behind the scenes, internal areas of IS&T, and business support groups; little to no customer-facing impact
| LOCAL or bounded to small group, roles, or department; group of customers of service offering or product, while it may be significant in size, is usually within a specific domain with well-established communications channels; we know who uses product or service offering and how they will react to changes
| WIDE impact to large segments of the MIT community, often with incomplete understanding of precise impact and user base, and without complete communication channels into community segments; customers often rely on affected products and service offerings for their day-to-day work
|
Risk to IS&T | Low Risk | Moderate Risk | High Risk |
How much will the retirement of the product or decommissioning of the service offering affect IS&T relationship with our customers? | Negligible to LOW; service alternatives are readily available, service continuity is not at risk, and changes can be backed out quickly and quietly
| MEDIUM, with failure to transition customers of potentially significant impact but affecting a limited audience; contingency and roll-back checklists are needed, but can be executed and communicated quickly in the event of a problem; limited, well-understood decommissioning and transition timeline is generally acceptable to stakeholders and customers
| HIGH risk is involved at this level; failure to transition customers will have significant negative impact on IS&T’s reputation and customer’s ability to get work done; formal mitigation plans, fully tested and approved contingency plans, and communications plans in the event of failures are called for
