Requirement Workflow Use Case Writing Process

I got this process from teaching PPT, I will support the link below.

1.Name the system scope and boundaries.
2.List the actors (Brainstorm)
3.List user goals for the system (becoming use case)
4.Capture the outmost summary use case to see "Who really cares" - seeking primary actors
5.Reconsider and revise summary use cases.Add, subtract or merge goals (Refining)
6.Select one use case to expand
7.Capture stakeholder interests and preconditions and guarantees (their requirements - there may be additional requirements)
8.Write the main succes scenario
9.List the extension conditions (Brainstorm)
10.Write the extension-handling steps
11.Extract complex flows to sub use case; merge trival sub use cases (Refining again)
12.Iterate and adjust

I think list number 1 to 6 will be helpful for SA28 who are now facing their exam on coming Monday.....

GOOD LUCK JUNIORS!!!!

Static Modelling & Dynamic Modelling in OOAD

Static Modelling : It is used to specify structure of the objects that exist in the problem domain (we will discuss this in next post). These are expressed using classes,objects and use case diagrams.It is Time Independent View.

Dynamic Modelling: It is Time Dependent View.It representing the object interactions during runtime , mostly represent by sequence, activity,collaboration and statechart diagrams.

Still confusing on System Actors and Internal Workers ?

Most of my juniors ask me about System Actor and Internal Worker –
a. Are they same?
b. What are Internal Worker and External Worker?
Usually those questions come up because of not getting the concept on Business workflow and Requirement workflow –

My classification is very simple (for dummies – like me). It is based on what we are focusing on .Let me explain with picture, cause single picture worth thousand of words.

First I pick Actors from case study. At this moment, I don’t care whether it is system or business actor. To pick Actors, there is definition – say – a person who is interacting with something. Something can be either business or system. For example, if we are discussing on Business workflow and there are a lot of people interact with the business. Those people may be (not are) Business Actors. If we are talking our requirements of business and to implement some system, people (not only human) who can interact (use) with our future system will become System Actors.

For instance, in manufacturing business, there are a lot of employees working in industry.
QCs, Engineers, Technicians, HRs, Managers, Accountants, Office Staffs, etc. Those people are working for this business – we call them Internal Workers of this business. So, in contrast, we can have External Workers . These External Workers may be Business Actors but not all External Workers are Business Actors. Same idea work for Internal Workers, not all Internal Workers are System Actors. It depends on who will use the system .

ANNOUNCEMENT FROM IVLE!!!!!!!!!!!!!!!!

Dear SA students,

Today I was shocked to find out that some of you have requested the internship company to increase your allowance. Please note that for such unprofessional behavior, ISS will take disciplinary action against you.

Binding ArrayList with DataGrid

I will discuss how to create an ArrayList of objects and bind it to a DataGrid control using DataSource property.

Step 1. Creating a Class

First step is to create a class. I call my class Developer, which is listed in Listing 1. It's properties are FirstName, LastName, Age, Skills, and Experience.

public class Developer

{
private string firstName;
private string lastName;
private int age;
private string skills;
private int experience;
public Developer(string firstName, string lastName, int age, string skills, int experience )
{
this.firstName = firstName;
this.lastName = lastName;
this.age = age;
this.skills = skills;
this.experience = experience;
}

/// First Name
public string FirstName
{
get { return this.firstName ; }
}

/// Last Name
public string LastName
{
get { return this.lastName ; }
}

/// Age
public int Age
{
get { return this.age ; }
}

/// Skill set
public string Skills
{
get { return this.skills ; }
}

/// Number of year experience

public int Experience
{
get { return this.experience ; }
}
}

Listing 1. Developer class

Step 2. Creating an ArrayList of Objects

Now next step is to create an ArrayList object of Developer class. Listing 2 adds 6 items to the ArrayList.

private ArrayList GetList()

{
ArrayList list = new ArrayList();
list.Add(new Developer("Mahesh", "Chand", 30, "C#,ASP.NET,Windows Forms", 10)) ;
list.Add(new Developer("Michael", "Gold", 35, "GDI+, ASP.NET", 15)) ;
list.Add(new Developer("Bhasker", "Das", 26, "VB.NET, Web Applications", 4)) ;
list.Add(new Developer("Ashish", "Singhal", 24, "ADO.NET, GDI+", 4)) ;
list.Add(new Developer("Neel", "Beniwal", 3, "C#,ASP.NET,Windows Forms", 0)) ;
list.Add(new Developer("Melanie", "Talmadge", 25, "Java", 2)) ;
return list;
}

Listing 2. ArrayList of Developer

Step 3. Binding with DataGrid

Now we can bind our ArrayList using DataGrid.DataSource property and DataGrid would understand what to display in its columns. The following code binds the ArrayList to DataGrid.

ArrayList list = GetList();

dataGrid1.DataSource = list;

Step 4. The Result

Now if I run my application, the output in DataGrid looks like Figure 1.
