Tender Quality Score

This tender notice clearly outlines the need for iXBRL tagging services but is severely incomplete due to the absence of crucial tender documents and evaluation criteria, which limits its transparency and fairness.

Score Breakdown

Legal Compliance100/100

The notice provides basic information required for a tender announcement. However, the absence of actual tender documents (e.g., ITT, contract terms, full instructions) means a comprehensive assessment of legal compliance with procurement regulations is impossible. The method for evaluating bids against the stated requirements is also missing.

Missing full tender documentation (e.g., Invitation to Tender, contract terms, detailed instructions).
Absence of explicit evaluation criteria for bids.
Clarity40/100

The description of the required service, objectives, scope of work, deliverables, and compliance standards is generally clear and well-defined within the notice. Provider requirements are also clearly stated.

Completeness83/100

The tender notice is severely incomplete as a standalone procurement package. It lacks essential documents that would typically accompany a tender, such as detailed instructions to bidders, full terms and conditions, pricing schedules, and crucially, evaluation criteria.

No documents attached or available for bidders.
Missing detailed evaluation criteria and methodology for assessing bids.
Fairness60/100

While the technical requirements seem reasonable for the service, the lack of evaluation criteria and full documentation could hinder fair competition. The requirement for 'on-site attendance as required by DBW' could potentially favor local providers, but it is not overly restrictive without further clarification.

Absence of evaluation criteria makes it difficult to assess how bids will be fairly compared.
'On-site attendance as required by DBW' could be a minor barrier for non-local or remote providers, depending on its frequency and necessity.
Practicality40/100

The scope of work, deliverables, and timing are practical and align well with the nature of iXBRL tagging services. The requirements for provider experience and use of HMRC-recognized software tools are also practical for ensuring a competent provider.

Data Consistency100/100

The information provided within the notice is consistent. The stated objectives align logically with the scope of work and expected deliverables.

Sustainability25/100

The tender notice does not include any explicit sustainability (environmental, social, or economic) criteria or considerations.

No green procurement criteria.
No social criteria.

Strengths

Clear and concise description of the required iXBRL tagging services.
Well-defined scope of work, objectives, and deliverables.
Specific technical and experience requirements for providers are clearly stated.
Estimated value and contract duration are provided.

Concerns

Absence of any attached tender documents, making the notice incomplete for bidding.
Lack of explicit evaluation criteria, hindering transparency and fair assessment of bids.
No stated mandatory exclusion grounds or detailed eligibility criteria beyond basic capability.
'On-site attendance as required by DBW' could be a potential barrier for remote or international providers.
No mention of how pricing will be submitted or evaluated.

Recommendations

1. Publish comprehensive tender documents including detailed instructions to bidders, full terms and conditions, and a clear pricing schedule.
2. Clearly define and publish the evaluation criteria and methodology for assessing bids against all stated requirements.
3. Clarify the frequency and necessity of 'on-site attendance' to ensure it is proportionate and does not unduly restrict competition.
