Iteration planning

However, there are some lessons learned. It is very important to communicate the ideas and benefits of the agile iterative development process to the entire project team and have buy-ins not only from the developers, but also from business analysts, the QA team, and end users. We only have a small QA team that supports many projects and end users are busy with their priorities. It is important to have some rough iteration planning upfront and have some idea about when QA and end users need to be involved in testing. If the plan has to change, inform QA and end users as early as possible. 

We said that iteration planning should be based on business values, risks, and complexity. Using our case study, CRS as an example, here is a... 

Enough has been said about the use case diagram and iteration planning. Now let s look at how to write use case specifications—text specification of use cases. 

Process parameters Library design Iterative planning based on results from virtual or experimental libraries... 

Statistical and algebraic methods, too, can be classed as either rugged or not they are rugged when algorithms are chosen that on repetition of the experiment do not get derailed by the random analytical error inherent in every measurement,i° 433 is, when similar coefficients are found for the mathematical model, and equivalent conclusions are drawn. Obviously, the choice of the fitted model plays a pivotal role. If a model is to be fitted by means of an iterative algorithm, the initial guess for the coefficients should not be too critical. In a simple calculation a combination of numbers and truncation errors might lead to a division by zero and crash the computer. If the data evaluation scheme is such that errors of this type could occur, the validation plan must make provisions to test this aspect. 

Use an iterative method based on successive linearization of the objective function to determine the optimum distribution plan for the product, DAB. Use an LP code to minimize total cost at each iteration. 

Iterations and increments must have clear objectives or else they can become a euphemism for structured hacking. Increments should be planned at multiple levels, from end-user increments to those that are internal to the development team or visible and demonstrated up to the project manager. Packages and their import relations are used to plan iterations and increments. 

The US Environmental Protection Agency (USEPA 1998) describes problem formulation as an iterative process with 4 main components integration of available information, definition of assessment endpoints, definition of conceptual model, and development of an analysis plan. These 4 components apply also to probabilistic assessments. In addition, it is useful to emphasize the importance of a 5th component dehnition of the assessment scenarios. The relationships between all 5 components are depicted in Figure 2.1. Note that the bidirectional arrows represent the interdependency of the different components and imply that they may need to be revised iteratively as the formulation of the problem is rehned. 

It is a mistake to think of the process of creating a project in linear terms first you have the idea, then you work out the idea in terms that can be actioned, then you plan the implementation stage, and so on. The creative process is usually a fairly jumbled one, with steps in the seeming logical sequence occurring simultaneously or In reverse order, and many iterations between steps.
