Define Transition Requirements:
BABOK Guide describes Transition Requirements as “capabilities that the solution must have in order to facilitate transition from the current state of the enterprise to a desired future state, but that will not be needed once that transition is complete. They are differentiated from other requirements types because they are always temporary in nature and because they cannot be developed until both an existing and new solution are defined.”
In simpler terms, transition requirements are what needs to be done to transition to the solution. Below is a list of various types of transition requirements.

Inputs:
Organizational Readiness Assessment: According to BABOK guide, it’s used to identify areas where the organization needs to add new capabilities to manage and operate the new solution. In case of Shell:
1. Shell considers it a business priority to diversify its business portfolio to include more unconventional fuels in order to meet the worlds increasing demand for energy whilst minimizing the impact on the environment. That’s why the need for the development of 'future fuels' is important.
2. One key challenge facing Shell is how to use its profits and accumulated reserves to promote sustainable business growth. Like all companies, Shell distributes some of its profits to shareholders in the form of dividends. It needs to invest any retained profit in developing the business in sustainable ways e.g. investing in new oil and gas drilling projects, refinery improvements, and research into, and development of, new products such as 'future fuels'.
3. Shell looks to contribute to sustainable development in three closely interconnected ways, each of which relates to long-term investment in R&D.

Requirements [Stated]: BABOK guide says, stakeholders will identify the information and processes they need during transition.
During the transition, all these actions have positive business benefits for Shell by reducing operational and financial risks, cutting costs through 'eco-efficiency', building closer relationships with customers, and helping the company to create new products to meet customers' needs.
1. Meeting the global energy challenge. This includes helping to:
Provide the extra energy required to sustain world economic development, including more oil and natural gas
Improve access to modern energy for the two billion people who currently live without it
Offer 'cleaner' products (e.g. low-sulphur petrol, GtL and diesel) and hydrogen products (hydrogen for new fuel cell vehicles)
Shift the world economy towards a low-carbon energy system by providing more natural gas (to replace coal), and by lowering the costs of alternatives like wind power, solar power, and biofuels (fuels from plants).
2. Working to improve the environmental performance of Shell operations: lowering emissions and impacts on biodiversity, and using less energy, water and other resources.
3.Acting to improve social performance: safeguarding employees' health and safety, reducing disruptions to communities, and creating lasting economic benefits e.g. by employing local people and using local contractors and suppliers.

Solution [Deployed]: According to BABOK guide, the deployed (or existing) solution will be investigated to understand what needs to be transitioned to the new solution. It may be necessary to elicit a description of the capabilities of the solution and perform some analysis tasks in order to ensure that current capabilities are fully understood.
Shell's R&D program provides expert advice for the company and to customers. It has a twofold emphasis. It looks to:
1. Make the best possible use of resources
2. Take maximum care of the environment.

Some research cannot be expected to pay for itself in any foreseeable time span. Many companies allocate a proportion of their research budgets to so-called 'blue-sky' investigations. These may produce spectacular commercial results in the shortest term, but their more
