Title -: Task Descriptions as Functional Requirements
Article summary
A software system is built based on the requirements. Therefore requirement elicitation is an important aspect. Functional requirements outline what the system do in order to achieve its goal. A functional requirement is an action which is performed by user / system to achieve a specific goal. The authors Marianne Mathiassen and had developed the Tasks & Support method, which uses annotated task descriptions. As per authors using this process computer and user shall accomplish together without indicating which actor performs.
which parts of the tasks. The author claims that with this approach higher-quality requirements are produced and are faster to produce and easy to verify and validate. This follows a similar phenomena as the definition of use case by Alistair Cockburn , ie use case is what the system does and how it interacts with the user. But tasked based requirement analysis delay splitting the work between the system and the user. In this approach it is considered as a decision to be made later.
The task has following components. The work area description states the formal requirement (R2: The system shall …). It also explains the overall purpose of the task, the environment, the user information. Further conditions and business rules of the task are captured, by as task preconditions or individual task steps, mostly by a pre condition.
Task can have several subtasks which supports the task. There is no sequence of operation in sub tasks. This provides greater flexibility when the requirements changes often. In the real world scenario , most of the time what could have greater possibility to change is how the businesses operated . Sin...

...analysis is done on task level it is easier to identify dependencies of each task for its completion , what needs to comply with, what are the non functional requirements to fulfill the tasks . The sub tasks in a task can be implemented sequentially or non sequentially.
The effective task analysis takes time. If adequate time is not allocated in the initial project planning ,it will run in to schedule variance. Further during testing it will be difficult to perform integration test . Further their will more hidden things which needs to attend and the difficulty in arriving on estimates.
After completing the task how the result of one task would impact other parts of the system.

A work breakdown structure is a key project deliverable that organizes the team 's work into manageable sections. The Project Management Body of Knowledge. defines the work breakdown structure as a "deliverable oriented hierarchical decomposition of the work to be executed by the project team”. Basically the work breakdown structure is something that is put together which defines the scope something that project team can understand. On the other hand, project requirement is kind of a document which tell management, what has to be produced and the exact date of completion. It also is based on responsibility factors. Requirements are the expectations which the product need to fulfill. Requirements are collected from the customer, stakeholders and Sponsor.
Another process activity useful for the prediction of changes is requirements-driven impact analysis or RIDA, for short. This analysis is used to pinpoint which software entities need to be altered in order to be able to implement a certain requirement (Lindvall, 1998). RIDA, which is conducted during the release planning phase, takes two variables into consideration. Firstly, there is the input, which refers to the existing complex system and the set of requirements. Secondly, there is the output, which represents the specific software entities that have to be changed to meet each requirement.
The first phase of standard agenda is Task Clarification. During Task Clarification the group members should understand the task of the meeting, and should be familiar with their personal roles. In case of the Traffic Commission, the task clarification was developed before the actual meeting. The committee members were familiar with the agenda and their personal roles.
Task 1 Vs. Task 4:If task 1 and task 4 are being completed, then task 1 will ...
It is a step of defining the goals of the projects and the results are aimed at reaching certain levels of productivity of customer satisfaction. The second stage is measure, and it is the stage of collecting data and facts and evaluating current operational performance. The third stage is analyze with the purpose of developing methods and theories that will best suit the solving of the problem; it is also a stage of detecting cause-and-effect ties of the processes. The fourth stage is improve, it is aimed at generating ideas for reaching the desired process improvement. Finally, there is the control stage that is about monitoring the operations to find out whether the process of improvement is smooth and the problems were solved (Meredith & Shafer,
The inter-temporal relationship between every task was specified in advance so the impact of delay of a task on other tasks could be calculated.
b. The duties include the major work functions to be accomplished; the quantity of work aspect is determined by the balance of those duties. Level of responsibility relates to the independence of the incumbent and to where the position will be placed in the organization hierarchy. Other aspects of job design include, when the individual will carry of responsibilities, the order of tasks, competencies the individual will need to perform the job, and training the individual will need to do the job and so
Knowledge task analysis: defining in detail what the worker needs to know in order to complete a specific job or task successfully.
Lack of coordination between the project management team causes the project to work at a much slower rate than estimated.
When the development process takes too long, it can happen that during the implementation process, the strategy has changed. This results in the fact that some of indicators have become outdated and requires new indicators. Measuring with incorrect indicators can divert an organisation from its strategy.
The Requirements Analyst captures and validates environmental requirements in Context Analysis and in Rest-of-Scenario Analysis, conducted iteratively with Functional Analysis.
The team implementing the new system were required to do both functional and systematic requirements thus affecting the implementation of the new system
A stream map can help determine what process are necessary and how to keep them running systematically. ⦁ Scheduling:- Considering both production and people, ask questions, such as how much product is required to produce for the customer in the required time? How many people and how many machines are required to done the job methodically and adequately.
PMBOK guide defines TM as the “Use of available time and your own productivity along with the appropriate planning and management of the project schedule” highlighting the link between Time Management and productivity and its closely knit relationship to scope and cost areas. Max Wideman presents a wider definition for TM as the “function required to maintain appropriate allocation of time to the overall conduct of the project through the successive stages of its natural life-cycle, by means of the processes of time planning, time estimating, time scheduling, and schedule control.” Ultimately at it’s core however, TM is about time, its planning and control during all stages of the project. A further look into Wideman’s definition of TM by means of identifying its importance throughout the entire project life-cycle (Initiation, planning, execution, controlling and close-out) is required. It is hoped that by analysing how TM tools and techniques can positively and negatively effect the different stages of the Project life cycle a better understanding of productivity, TM and project success will result.
Using this you can keep keen eye on activities that trigger start of other activities. Delay in those might lead to delay in the overall project.
