Ok cv,
não percebi qualquer furo nele. Se você puder identificá-los … 
Vc pode fazer uma analogia ao UP com uma farmácia, onde a farmácia dispõe de uma infinidades de medicamentos, e o paciente escolhe qual ou quais estarão sendo úteis para o seu tratamento, a mesma coisa com o UP, dispões de muitos artefatos opcionais, todos são opcionais, menos o código (claro). Desse ponto de vista como o processo é iterativo, e o manifesto ágil propõe isso, então estaria perfeitamente adaptável, lógico que no processo ágil você não vai colocar artefatos e atividades desnecessárias, você vai escolher aqueles que melhor se adequa a metodologia, se for 1 ou 2, ótimo,contato que siga estes principios:
:arrow: Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
:arrow: Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.
:arrow: Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
:arrow: Business people and developers must work together daily throughout the project.
:arrow: Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
:arrow: The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
:arrow: Working software is the primary measure of progress.
:arrow: Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
:arrow: Continuous attention to technical excellence and good design enhances agility.
:arrow: Simplicity–the art of maximizing the amount of work not done–is essential.
:arrow: The best architectures, requirements, and designs emerge from self-organizing teams.
:arrow: At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
