Requirements Analysis and Specification Writing are sciences practiced by many, mastered by surprisingly few. And yet, the payoff from achieving excellence in these areas is large. The two aspects, Requirements Analysis and Specification Writing, are treated as separate but related topics.
The Requirements Analysis module addresses the techniques used to capture, validate and gain a complete understanding of requirements communicated at all stages of the system life cycle. The two-day Specification Writing module addresses in detail the conversion of individual requirements into effective requirements specifications. The course focuses on the structure and language of requirements specification.
The Requirements Analysis module provides highly effective tools for both the capture of requirements, and for validation of those requirements, in any scenario involving the receipt of requirements from one or more stakeholders who have a need. A workshop approach is used extensively in this module, to maximize learning and practical application. Effectiveness of the techniques, collectively comprising a complete methodology, is independent of the domain of application, and independent of the specifics of the need. These techniques have been used with great success.
The Specification Writing module provides detailed instructions on the conversion of requirements into highly effective requirements specifications. Issues of structure (organization of information) and the use of (English) language throughout a requirements specification are examined in considerable detail. Public domain specification standards are overviewed and compared. High quality templates/guides, with examples, are provided for the specification of systems, software, interfaces and services, respectively. The course is strongly activity-oriented throughout. The techniques of specification writing that are taught have been used to great effect in scenarios that include acquisition, supply, product definition (both hardware and software), enterprise internal projects, business analysis and diverse engineering projects, large and small.

Q. What is the difference between the Requirements Engineering and the Requirements Analysis & Specification Writing training?
The Requirements Engineering (RE) course is primarily designed for people whose first language is not English. As such, it is not offered in most countries where English is the native language.
Q. Which model and method will we use for analysis?
The model and method used in the course (and in real life) is illustrated and explained in the three files attached below.
Q. What skills can be gained by attending this course
The skills you will develop are the skills to effectively transform a starting point of one or more stakeholders having a problem (documented or not) into a statement of that problem suitable for driving development of an optimum solution. The problem may be of a business need or opportunity, or of any other nature whatsoever.
Q. What is the degree of overlap between PPI's five-day Systems Engineering course and PPI's five-day Requirements Analysis & Specification Writing course?
In that both Requirements Analysis and Specification Writing are critically important sub-disciplines within Systems Engineering, these disciplines are covered in both courses.
In the 5-day Systems Engineering course, Requirements Analysis is put in context in the first two days of the course. Then, 1.7 days is devoted to "how to do requirements analysis - capture and validation of the information content of requirements". This depth of coverage is sufficient for delegates to go away with new insights, and importantly, new skills, in performing Requirements Analysis. Courses are used extensively, based on a single system that is taken through Requirements Analysis then subsequently Design, in workshop format.
In the 5-day Systems Engineering course, Specification Writing is put in context in the first two days of the training. Specification writing is then touched upon incidentally in Requirements Analysis, especially in parsing analysis, and in the "clean-up" activity, a related handout for which lists problematic English: parts of words, words and phrases, and the checks that are done regarding adequacy of language in relation to use of these words (etc.).
In the 5-day Systems Engineering course, a revised requirements specification for the course system is distributed to, and inspected by, delegates, on the fourth day of the training. More general advice on specification writing is then provided on the fifth (last) day of the training, over 10-15 minutes.
In the 5-day Requirements Analysis and Specification Writing course, Requirements Analysis and Specification Writing are put in context in the first 0.8 days of the course. Focus is then given to the types of requirements and their significance to the roles of requirements analyst, specification writer, and designer. This session culminates in a workshop exercise. Then, 2-2.5 days are devoted to "how to do Requirements Analysis - capture and validation of the information content of requirements". This is a significantly greater depth of coverage compared with the Systems Engineering course. Course exercises are again used extensively, based on a single system, almost always a different system to the system used for the Systems Engineering training. There are more, and longer, course exercises in Requirements Analysis compared with Systems Engineering training. Overall, RA&SW5D provides greater depth in Requirements Analysis than does the Systems Engineering.
The feedback from people who have participated in both courses has been mostly that they have appreciated the revision and extra depth in Requirements Analysis. However, about 10% of people have regarded the overlap as excessive for their purposes.
In the 5-day Requirements Analysis and Specification Writing course, hugely more coverage is given to the structuring of system and software requirements specifications, and specifications of services. Similarly, almost a day is devoted to advice on the use of language (English) in expressing requirements - pitfalls and pointers. There is also substantial coverage of writing non-requirements sections of requirements specifications - scope, applicable documents, definitions (etc.), notes.
Q. Can the Requirements Analysis & Specification Writing training be shortened for on-site delivery?
Yes it can. This is a course that can be shortened to 2-3 days and still deliver significant learning. If the training is to be shortened, we recommend Requirements Analysis two days and Specification Writing one day, for still a high level of learning, or a combined Requirements Analysis & Specification Writing 2-Day course at about 1.3 days Requirements Analysis and 0.7 days Specification Writing. Learning will be close to linearly proportional to course duration.
Another option is to split the longer course into RA-3 day and SW-2 day delivered in separate weeks.
Q. I am an industrial engineer currently working as a business analyst. Will this training be relevant to my line of work (in the IT field), or is it more aimed at the technical design of physical products?
In its use of formal examples, the training is oriented towards physical systems of a wide variety of kinds. There are IT examples and pure software examples, however, the overall orientation of the examples is not strongly IT. The training is not oriented towards technical design at all; the training is concerned entirely with requirements capture, validation and specification, to drive acquisition or development and/or verification, as applicable, irrespective of application or technology.
Many Business Analysts (BA's) have participated in the training which has been delivered on-site to groups who have been made up of primarily BA's, such as EDS, Ericsson, CSC, LexisNexis, Sperry Univac, Nokia Siemens Networks (Poland), Alcatel-Lucent (Belgium), CISCEA (Brasil), NATS (UK), etc.
We believe that the course will be of substantial benefit to any BA's. There is much content that aligns in context and purpose with the Business Analysis Body of Knowledge® (BABOK®) Guide. This tends towards greater rigor, and some of the methods are more robust than those commonly used by BA's, but are equally applicable to BA's. So the training provides to the BA professional an opportunity for professional growth.
In summary, the BA should get a lot out of the course training as has been the history of participation of the BA's so far.
