Supplier requirements and viability
Alignment with the Company’s Business and IT
Strategy
• Should support the organization’s business and IT strategy
• The business requirements associated with the solution being
sought should link to goals and objectives identified in the
company’s business and IT strategy
Bina Nusantara
Definition of the information requirements
• System and information requirements should be evaluated to
determine if they are current and complete.
• The fast pace of business, requirements can change quickly.
• Prototypes

Incomplete system design
Inefficient processing performance
Inadequate application controls
Inadequate documentation
Ineffective implementations
Feasibility Studies
• Should be reviewed to ensure that the selected solution not only meets the
requirements but also is compared and contrasted with the feasibility of the other
solutions.
• Economic feasibility
– Should be reviewed and approved by an involved and knowledgeable sponsor prior to
the final decision to ensure that the “make versus buy” question is effectively
evaluated.
• Technical feasibility
– Should be reviewed and approved by an involved and knowledgeable sponsor prior to
the final decision to ensure the organization’s ability to implement and support the
selected solution

Specific detailed measures
Inspections
Functional tests
Workload trials
User requirements
Performance expectations
Term of contract
Conformity with existing information and system
architecture
• This control is directly correlated with the evaluation of technical
feasibility and the business information elements.
Bina Nusantara
Adherence to security and control requirements
• A complete understanding of the company’s security and control requirements is
needed to ensure that the selected solution is appropriate
• Company security policies and applicable regulations need to be reviewed during
the selection process to ensure that security and control requirements are
considered in the selection process
• System acquisitions and implementations become more difficult when these
requirements are not well understood or documented. The result will be missed
security functionality or poorly implemented security.
Bina Nusantara
Knowledge of Available Solutions
• System development and acquisition efforts become more focused
on a specific solution due to the knowledge or experience of the
participants.
• By focusing on a specific end result, other alternative are not
considered. By not considering other alternatives, the selected
solution may increase cost, scope, or the timeline for the project
because they did not meet basic requirements such as
incompatibility with the current company infrastructure or business
practice.
Bina Nusantara
Understanding of the related acquisition and
implementation methodologies
• Acquisition methods
• Selected implementation methods
Bina Nusantara
Involvement and buy in form the user
• User involvement and buy in is critical
• Without user involvement, requirements will be missed and they will
not support new systems.
• Increases awareness of the criticality of user support and buy in.
• System implementation success relies on effective communication.
Bina Nusantara
Supplier requirements and viability
• The acquisition process should ensure that the selected vendor
meets the vendor requirements of the organization as outlined in
the proposal.
