Through the new practice guide and PMI-PBA certification, PMI will drive an awareness of the role globally that IIBA® has simply not had the resources to do
To obtain a PMI-PBA, first you complete an application that verifies you meet the following requirements:
Minimum of 3 years (4,500 hours) of business analysis experience within the past 8 consecutive years if you have a bachelor’s degree. (Or 5 years/7500 hours of experience if you do not.) (For comparison, the CBAP® requires 7,500 hours of experience and the CCBA® 3,750.)
2,000 hours working on project teams within the past eight consecutive years.
35 business analysis education (contact hours).
Scrum
works very fine within small teams, adding new functionality in an incremental
way. But how to transform traditional developers into a scrum way of working
and how to align the multiple teams? How to maintain piles of legacy code? And
how to go about solving the specific issues the high tech industry has with
Agile? The session ‘Scrum is not enough!’ will give an overview of these challenges
and presents best practices to address them.
Welke kennis wordt veel gevraagd?
Antwoord: IT-ers met kennis van Cisco, Oracle, Java, SAP, Peoplesoft, testen, informatie
analyse zijn gewild en kunnen over het algemeen snel aan opdracht geholpen worden.
Ook andere expertises zijn over het algemeen prima in te zetten.
Is a use case a requirement or just a story?
Is a scenario just another name for a use case?
Is a use case a formal, semi-formal, or informal structure?
Is there a linking structure for use cases, or do they just come in piles?
make use cases “rigorous
People want a fairly informal medium in which to express their early thoughts
Using these semi-formal structures, we can both
Assert that use cases really are requirements and need a basic structure, and also
Allow people to write whatever they want when they need to.
Here is the semi-formal structure
Linking use cases to actors’ goals
If the software supports those goals, the software will yield the greatest business value.
goals sometimes fail
failure handling
Therefore, a use case is structured into two sections: the sequence of actions when everything goes well, followed by various small sequences describing what happens when the various goals and subgoals fail.
Why do we write things in the use case that are not externally visible behaviors?
contract between stakeholders
Here are four key pieces of advice that you should note from the evolution of use cases.
there remained a split between those who still wanted to keep use cases short and informal and those who wanted them to be detailed
The Stakeholders and Interests model fills the holes in the Actors and Goals model
Prepare for Multiple Formats
Only Use Them When the Form is Appropriate
Be Aware of Use Case Limits
Use cases should not be used to describe UI designs
use case is normally intended as a requirements document, and the UI design is a design
The same system feature is likely to show up as a line item in multiple use cases
Use cases have a basic mismatch with feature lists
Use cases are not test plans or test cases
Avoid the Standard Mistakes in Use Cases
The two most common and most costly to the project are including too many details and including UI specifics
it’s just that by the time I get subgoals at a good level and remove the design specifics, the task is less than nine step
The greatest value of the use case does not lie in the main scenario, but in alternative behaviors
If the main scenario is between three and nine steps long, the total use case might only be two or three pages long, which is long enough.
readable use cases might actually get read
