5 A day in life of a SharePoint architect / dev We are shooting at a moving target while wearing blindfolds, without knowing what the target looks like, where it is, or what type of ammo we need to use. In fact, we don t even know if we re in the right shooting range. Bjørn Furuknap, SP consultant and blogger

6 Requirements management Reqs document Time/cost estimation Change management (Agile) Holy Grail (and your life insurance)

7 Requirements document Contains detailed explanation of all use cases (scenarios) Contains descriptions of all user roles (and permissions) Contains description of all inputs and outputs Contains descriptions of all processes Contains predicted extensity of use and concurrency situations Describes what can be implemented as a no code solution, and what has to be developed

8 Requirements document Ensures that all the people involved in the process really understand the process Ideally done by a business analyst and an architect Contains yours and customer s signature

9 NO SPECS NO CODE SharePoint empowers users to do things alone -> NO SPECS - NO CODE Customer s processes are at very best loosely described -> NO SPECS - NO CODE Customers don t understand the complexity of the solution they require -> NO SPECS NO CODE But we have agreed that you will do that NO SPECS NO CODE If we kick off immediately, we will save time (yes, and Elvis is still alive) -> NO SPECS NO CODE Protect yourself AND your customer

10 Time and Costs estimation

11 Time and Costs estimation First 80% of the project consumes 80% of the budget Last 20% of the project consumes another 80% of the budget Bill Gates

12 Time/Budget consumption according to Gates Budget consumption (%) Project completion (%)

13 Some questions to think about How long do you need for the development? Break the requirements document down to deliverables and blocks. Do you have everything in requirements doc? How long did you write the requirements doc? Who did the architecture? When? How about some testing? You have bugs? When are you going to fix them? Who is going to deploy the solution? To which server? When? Do you practice code reviews? Who is going to the meetings? How often?

14 Making a Time / Costs estimation Iterations Design Development Testing Debugging Review Project Mgmnt. Deployment

15 Making a Time / Costs estimation Event receiver? Can be done in 1h. (Best case) Maybe in 2h (Most Likely) Or sometimes in a day (Worst case) E ML 4 B W 6

17 Change Management

18 Change Management I have deleted that field. We didn't need it anymore.

19 Change Management I have deleted that field. We didn't need it anymore. We have changed the workflow - process description was wrong

20 Change Management I have deleted that field. We didn't need it anymore. We have changed the workflow - process description was wrong I've just changed the list name, why is the event receiver not working?

21 Change Management I have delete that field we didn't need it anymore We have changed the workflow - process description was wrong I've just changed the list name, why is the event receiver not working? THEY CAN DO THAT!

22 Change Management Change Standard Change SharePoint Change Deal within CM Crucial for the solution? Yes: Deal within Architecture No: Deal within CM

23 Architecture of SharePoint solutions Requirements management Deployment Solution Architecture Dev Cycle Quality Assurance Development Testing

24 Architecture of SharePoint solutions

25 A SharePoint Solution Workflows Silverlight Ajax Timer Jobs Managed Code Event Receivers Office Clients InPage SP Solution!NET

26 What is wrong with this web part?

27 Solution Architecture InPage Event Rcv. Workflow Timer Service(s) WCF, ASMX, REST Business Logic Layer I RIA NET Office!Net Data Access Layer DA Common Functions Core Functions (Logging, Exceptions) SP DATA

28 Solution Architecture InPage Event Rcv. Workflow Timer Service(s) WCF, ASMX, REST Business Logic Layer I RIA NET Office!Net Data Access Layer DA Common Functions Core Functions (Logging, Exceptions) SP DATA

29 Solution Architecture: InPage

30 Solution Architecture: Client Side

31 Solution Architecture: Client Side

32 Solution Architecture: Client Side People want a good looking and good performing application Increase performance: Async calls Client Side Caching Predictive Loading Reachability as an issue Reach HTML AJAX Silverlight Capability

33 Error Handling and logging

34 Demo: Logging in ULS

35 Configuration No Hard-Coded configuration Web.Config only in life threatening situations Or

36 SPG Configuration Manager

37 Multilingualism

38 Multilingualism OOB features

39 Multilingualism user preferences

40 Multilingualism ML configuration list

41 Other architecture considerations Architecture documentation Standard Design Patterns Avoid 3rd Party libraries Solution Technical Documentation

42 SharePoint development Requirements management Deployment Solution Architecture Dev Cycle Quality Assurance Development Testing

43 Development Standard coding conventions (Microsoft) Define standard core libraries (reuse standard functionality) own or SPG Use standard VS 2010 SharePoint project templates Follow the SharePoint rules of game field names, required fields, descriptions, translations Follow architecture guidelines logging and exception handling Use a very defensive approach you never know when will somebody delete a field

44 Development Use SharePoint tools (SharePoint Manager, ULS Viewer, SPDiag) Don t use 3 rd party components if you don t really have to Use Linq SPMetal is good

45 Testing SharePoint Solutions Requirements management Deployment Solution Architecture Dev Cycle Quality Assurance Development Testing

46 Unit Testing, Integration Testing First line of defense Not possible OOB with Visual Studio 2010 Unit Testing Custom Unit testing solutions Moles Framework Custom Console App Continuous Integration Testing (TFS Team Build, Cruise Control)

47 UI, Stress and Load Testing Coded UI Tests Load Tests Stress Tests

48 Manual tests Still the most important tests Test cases document Microsoft Test Manager -> Helps with Problem reproducing fight
