program by comparing bene ts derived and the costs incurred It is a way to estimate value expressed as worth of development in terms of impact on economy, that is, the impact of the stimulus package on the economy On a more granular scale, it can be applied to determining completion of life cycle cost comparisons of project alternatives Business Case Analysis (BCA) This is a comparative analysis that presents facts and supporting details among competing business alternatives For instance, the DoD application says that the BCA should facilitate a determination whether to implement a Performance Based Logistics type arrangement by comparing the Government s cost of supporting the initiative versus the contractor s cost of supporting the items or material There are two types abbreviated (rough order magnitude, ROM) and nal BCA Requirements Analysis (RA) In systems engineering and software engineering, this encompasses those tasks that go into determining the needs or conditions to meet for a new or altered product, taking account of the possibly con icting requirements of the various stakeholders, such as bene ciaries or users Requirements analysis is critical to the success of a development project Requirements must be actionable, measurable, testable, related to identi ed business needs or opportunities, and de ned to a level of detail suf cient for system design Project and Program Management (PPM) Project management is the discipline of planning, organizing, and managing resources to bring about the successful completion of speci c project goals and bjectives Program management is the same discipline applied to a broader scope and scale, multiple projects, or multiple tasks Enterprise Resource Management (ERM) This term is used to describe comprehensive resource management throughout the enterprise It includes planning and organizing and controlling resource application and various rates of consumption It is a subset of enterprise performance optimization (EPO) Performance Improve Strategizing (PIS) The act of strategizing how to improve performance We used to call this performance improvement engineering (PIE), but to emphasize that this is an executive and management responsibility and that it is strategic, we changed the term It is a systematic plan of action Problem Solving (PS) The Wikipedia de nition [14] is a part of thinking considered the most complex of all intellectual functions; problem solving has been de ned as [a] higher-order cognitive process that requires the modulation and control of more routine or fundamental skills It occurs if an organism or an arti cial intelligence system does not know how to proceed from a given state to a desired goal state It is part of the larger problem process that includes problem nding and problem shaping Problem solving is of crucial importance in engineering when products or processes fail, so corrective action can be taken to prevent further failures Forensic engineering is an important technique of failure analysis which involves tracing product defects and aws Corrective action can then be taken to prevent further failures .

We suggest that problem solving begins with performance problem analysis (PPA) to produce a problem de nition on which to apply creative and innovative skills to produce a solution Decision Making (DM) The Princeton de nition [15] is the cognitive process of reaching a decision; a good executive must be good at decision making Planning (P) The Princeton de nition [15] is an act of formulating a program for a de nite course of action; the planning was more fun than the trip itself Sensemaking and Predicting (SP) Sensemaking is the ability or attempt to make sense of an ambiguous situation More exactly, sensemaking is the process of creating situational awareness and understanding in situations of high complexity or uncertainty in order to make decisions It is a motivated, continuous effort to understand connections (which can be among people, places, and events) in order to anticipate their trajectories and act effectively [16] Predicting is the act of reasoning about the future Financial Management (FM) This is management related to the nancial structure of the company and therefore to the decisions of source and use of the nancial resources, which is re ected in the size of the nancial income and/or charges [17] Work Design (WD) One de nition has it that in organizational development (OD), work design is the application of Socio-Technical Systems principles and techniques to the humanization of work We have a more speci c de nition to add in context with our enterprise performance optimization process ork is performed by people, by technology, and by combinations such that people may use technology or operate technology to complete a task as evidenced by speci c outcomes Using the process modeling lexicon, a process is made up of activities and an activity may be equated to a task or subtask Work design combines process modeling and the attribution of people and technology to the model such that (1) individuals may be assigned who possess certain skills, knowledge, and pro ciencies, (2) under constraints of budget and time, (3) to produce superior results Job models may be the products of work design that become inputs to organization development that is akin to the process of organization design Process Engineering (PE) This term is customarily employed in chemical and biological process industries to de ne activities that produce an end result That is really the same way that we use the term, although we apply the IDEF0 de nition to de ne processes as a relationship of activities with associated inputs, controls, outputs, and mechanisms Our de nition applies to all processes Knowledge Management (KM) The Wikipedia de nition [18] comprises a range of practices used in an organization to identify, create, represent, distribute and enable adoption of insights and experiences Such insights and experiences.

essentially cutting it in half By the repeated halving principle, we know that the number of iterations will be O(1og N ) For an unsuccessful search, the number of iterations in the loop is bog N] + 1 The reason is that we halve the range in each iteration (rounding down if the range has an odd number of elements); we add 1 because the final range encompasses zero elements For a successful search, the worst case is hog N] iterations because in the worst case we get down to a range of only one element The average case is only one iteration better because half the elements require the worst case for their search, a quarter of the elements save one iteration, and only one in 21 elements save i iterations from the worst case The mathematics involves computing the weighted average by calculating the sum of a finite series The end result, however, is that the running time for each search is O(1og N ) In Exercise 620 you are asked to complete the calculation For reasonably large values of N, the binary search outperforms the sequential search For instance, if N is 1000, then on average a successful sequential search requires 500 comparisons The average binary search, using the previous formula, requires bog N] - I , or eight iterations for a successful search Each iteration uses 15 comparisons on average (sometimes, 1; other times, 2), so the total is 12 comparisons for a successful search The binary search wins by even more in the worst case or when searches are unsuccessful If we want to make the binary search even faster, we need to make the inner oop tighter A possible strategy is to remove the (implicit) test for a successful search from that inner loop and shrink the range to one item in all cases Then we can use a single test outside the loop to determine whether the item is in the array or cannot be found, as shown in Figure 612 If the item we are searching for in Figure 612 is no larger than the item in the mid position, it is in the range that includes the mid position When we break the loop, the subrange is 1, and we can test to see whether we have a match In the revised algorithm, the number of iterations is always b o g ~1 because we always shrink the range by half, possibly by rounding down Thus the number of comparisons used is always Llog N1+ 1 Binary search is surprisingly tricky to code Exercise 66 illustrates some common errors Note that, for small N, such as values smaller than 6, the binary search might not be worth using It uses roughly the same number of comparisons for a typical successful search, but it has the overhead of line 13 in each iteration Indeed, the last few iterations of the binary search progress slowly We can adopt a hybrid strategy in which the binary search loop terminates when the range is small and applies a sequential scan to finish Similarly, people search a phone book nonsequentially Once they have narrowed the range to.
