In general terms, the functional specification states what the proposed system
is to do, whereas design is how the system is to be constructed to meet the
functional specification. However in writing it, some consideration of design
issues must take place, to ensure a realistic system is specified.
This module teaches students how to collect design information into a
functional specification. Microsoft Official Curriculum (MOC), available to IT Academies at a discounted price, is professional courseware intended for IT professionals and developers who build, support, and implement solutions by using Microsoft products and technologies. MOC is designed to cover the topics that employers know are mission-critical in the real world.
The Planning Phase of the MSF Process Model culminates in the Project Plan
Complete Milestone. One of the primary deliverables of this milestone is the
functional specification. The functional specification describes the solution in
sufficient detail for the development team to implement it.

Functional testing is a type of black box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered (not like in white-box testing).
Functional testing differs from system testing in that functional testing "verif[ies] a program by checking it against ... design document(s) or specification(s)", while system testing "validate[s] a program by checking it against the published user or system requirements"...
Software requirements are documentation that completely describes the behavior that is required of the software-before the software is designed built and tested.
Requirements analysts (or business analysts) build software requirements specifications through requirements elicitation.
Interviews with the users, stakeholders and anyone else whose perspective needs to be taken into account during the design, development and testing of the software
Observation of the users at work
Distribution of discussion summaries to verify the data gathered in interviews...
Quality means “conformance to requirements”
The best testers can only catch defects that are contrary to specification.
Testing does not make the software perfect.
If an organization does not have good requirements engineering practices then it will be very hard to deliver software that fills the users’ needs, because the product team does not really know what those needs are.
Software systems Ubiquitous, used in variety of applications
- Business, engineering, scientific applications
Simple to complex, internal to public, single function to enterprise-wide, one location to distributed, batch or real time, informational to mission-critical,…
A review is any activity in which a work product is distributed to reviewers who examine it and give feedback.
Reviews are useful not only for finding and eliminating defects, but also for gaining consensus among the project team, securing approval from stakeholders, and aiding in professional development for team members.
Reviews help teams find defects soon after they are injected making them cost less to fix than they would cost if they were found in test.
All work products in a software project should be either reviewed or tested.
Most software is built in organizations for people with specific needs.
A stakeholder is a anyone who has an interest (or stake) in the software being completed
A user is someone who will need to use the software to perform tasks.
Sometimes stakeholders will be users; but often the stakeholder will not use the software.
For example, a senior manager (like a CEO - chief executive officer or CTO - Chief technology officer in a company) will usually have a stake in the software that is built (since it affects the bottom line), even if she won’t ever use it....

What drives development? How much of the process is determined by people’s assets, skills, and
opportunities; by the regulatory environment; or by the location, arrangement, and dynamics
of interconnected economic activities? Whereas the first two of these criteria have attracted
considerable attention, much less research has been directed at the influence of the intensity and
degree of concentration of economic activity. A study of how industrial clusters are organised and
function should contribute to a better understanding of this issue.
This paper describes our system for generating Chinese aspect expressions. In the system, the semantics of different aspects is characterized by specific temporal and conceptual features. The semantic applicability conditions of each individual aspect are theoretically represented by an aspect selection function (ASF). The generation is realized by evaluating implemented inquiries which formally define the ASFs, traversing the grammatical network, and making aspect selections.
Dialogues may be seen as comprising commonplace routines on the one hand and specialized, task-specific interactions on the other. Object-orientation is an established means of separating the generic from the specialized. The system under discussion combines this objectoriented approach with a self-organizing, mixed-initiative dialogue strategy, raising the possibility of dialogue systems that can be assembled from ready-made components and tailored, specialized components.

This is the second book containing examples from the Theory of Complex Functions. The first topic
will be examples of the necessary general topological concepts. Then follow some examples of complex
functions, complex limits and complex line integrals. Finally, we reach the subject itself, namely the
analytic functions in general. The more specific properties of these analytic functions will be given in
the books to follow.
Functional Unification Grammars (FUGs) are popular for natural language applications because the formalism uses very few primitives and is uniform and expressive. In our work on text generation, we have found that it also has annoying limitations: it is not suited for the expression of simple, yet very common, taxonomic relations and it does not allow the specification of completeness conditions. We have implemented an extension of traditional functional unification. This extension addresses these limitations while preserving the desirable properties of FUGs.
We propose a method for analyzing long complex and compound sentences that utilizes global structure analysis with domain-specific pattern grammar. Previously, long sentence analysis with global information used the following methods: two-level analysis--global structure analysis of long sentences with domain-independent function words and parsing of their constituents[Doi et al., 1991], and pattern matching--adaptation of domain-specific fixed pattern to input sentences. By utilizing domaindependent information the latter method could analyze long sentences of that domain.
Engineering often involves applying a consistent, structured approach to the solving of problems.
A general problem-solving approach and method can be defined, although variations will be required
for specific problems.
Problems must be approached methodically, applying an algorithm, or step-by-step procedure by
which one arrives at a solution.
