Estimation Techniques

Hi there,
We are currently looking at ways of estimating the time and money
required to complete a Forte project. We are looking at using one or more
of Forte, Web Enterprise Designer, and Conductor.
Has anybody found/developed a technique that seems to work well in one or
more of these areas?
Thanks in advance for your reply.

Estimation Technique for ABAP programmimng

Hi,
I would like to know if there are any formal software estimation techniques that may be used for ABAP development.The commonly used estimation techniques such as Function Point/LOC etc do not seem to fit in.We currently use WBS methodology but here again it is left to the discretion of the developer to estimate for the lower level tasks .
Any suggestions on a technique that would best suite the vast style of programming varying from reports to module pools/ sapscripts/bdc/user exits etc etc...
Regards
Rani

Thanks Serdar for the link . I will take a look at it.
In the recent past I have faced several instances where I have had to give estimates to the clients for ABAP development. Though we use WBS (Work Breakdown structure), but that also is gut feel based and based on the experience of the developer involved.I discussed this with several friends in the SAP world but no one had a real answer.
I tried using FPA which is a more unversally acceptable estimation technique.
The main problem I run into when trying to do some kind of estimation for ABAP development using FPA technique is:
1. There is no logical data model available in SAP
2. As a developer building custom programs, there is already so much code/functions available , the varying levels of reuse makes it difficult to estimate
3. Several program such as for BDC the code gets automatically generated and then we adapt this code further based on the requirements, so again estimation becomes difficult.
I would request some one from SAP to respond on how they do estimation & what technique do they use :
1) for new modules & functionalities that they build
2) for enhancement/bug fixes that they do to existing applications
Rather I would like to use the SDN forum as a means to formulate an estimation technique suitable for ABAP devlopment.
Hoping to receive some wonderful suggestion from all the brilliant people out there.
Cheers
Rani

Oracle Database Size Estimation Technique

Hello All,
I am planning to estimate a database in Oracle. Its a fresh database and will not take any data from any other legacy or flat file systems.
Do anyone of you can provide me with a checklist sort of thing which will enable me to estimate the size of my database considering its future growth as well?
Or if you have a document which guides to do the estimation of the size of Oracle database, could you please share it with me as well?
Thanks in advance
Himanshu

This estimation will depend on your installation type and your configuration like your OS, Oracle edition, release information. For example below information is from Oracle® Database Installation Guide
10g Release 2 (10.2) for Linux x86 Chapter 2 Preinstallation Tasks - http://download.oracle.com/docs/cd/B19306_01/install.102/b15660/pre_install.htm#sthref95
# 400 MB of disk space in the /tmp directory
# Between 1.5 GB and 3.5 GB of disk space for the Oracle software, depending on the installation type
# 1.2 GB of disk space for a preconfigured database that uses file system storage (optional)
Best regards.

State space of continuous systems with discrete mesurements

Hello everyone,
I want to implement some estimation techniques for continuous systems using discrete measurement but I'm having some trouble finding a communion between the two concepts in labview. Basically what I want to do is to solve the ODE for the system continuously, while just getting measurements every some time step (bigger that the ODE solver), then using both quantities for state estimation. Any advice on this?
Thank you,
Juan E Tapiero

Re: Forte Estimating Metrics

Greg,
In my experience, the class-count metric is a poor one for time estimation,
for four reasons:
1. The actual time/class is very domain- and implementation-
sensitive. Industry averages are fairly unhelpful, unless
you happen to employ average practices and work in domains
of "average" complexity (whatever that means!)
2. It does not account for the overall size of the project; the
larger the project, the lower overall productivity is.
3. It requires that a fairly detailed design be done already, which
represents a fair amount of the total effort; as an estimation
tool, it is only useful in the latter stages of a project.
4. Lorenz's research is based on a very small sample; 18 projects are
hardly enough to have statistical validity.
(I almost included a fifth point, but it is hardly worthy: class-counting
can be spoofed. Awareness of the use of class-count as a metric can give
developers a motive to either artificially increase or decrease the class
count, depending on other motivating factors.)
I would recommend function point analysis as a more general purpose tool
for project management. Using a good statement of the requirements, FPA
generates a measure of the size of the application in terms of function
points. This is independent of the implementation; it measures the
behaviours of the application, rather than the particulars of design
or implementation, such as class count or lines-of-code. Note that
expected productivity varies as a function of the overall size of a project.
FPA has been used as part of the study of literally thousands of
software projects, so the conclusions drawn from FPA studies done
by Capers Jones at Software Productivity Research have some
statistical credibility.
Looking at the general productivity numbers gathered by SPR
(http://www.spr.com), there are some productivity measures that
cover many languages, including Forte. In terms of lines-of-code
per function point, Forte is 3 times more productive than C++.
In terms of overall productivity (function points / man month), there
are too many variable factors to make a simple statement of relative
productivity levels between C++ and Forte meaningful. This has a lot
to do with the Forte object model and run-time system, which, in certain
problem domains, provides a lot of function points (or equivalent)
"for free." In other words, if you can use Forte's plumbing package,
you're automatically more productive. Providing the equivalent in
C++ would be a daunting task (I should know -- I've done it!)
The best method of determining your productivity is to measure it. There
are many factors that affect the overall productivity of your software
organisation; the programming language choice is just one. Using metrics
drawn on industry averages concerning just ONE variable in the product
development process is not terribly useful in project management.
If you are looking for an extremely rough number that is more defensible
that the good old "gut feel" technique, then class counting is probably
the least intrusive on the development process.

Transportation time using condition technique!!

Hi All,
Can anyone tell how transportation time is calculated using condition technique (APO)? we have defined following in access sequence for scheduling
Plant
Destination country
Spd trans. zone
Shipping Conditions
Weight group
Factory Calendar ID
Now if no transportation lane is defined between plant A and ship to party B. Then how system is going to calculate the delivery date? where do we define transportation time between A and B or how it is getting calculated?

HI,
You can define a specific transporation duration in the condition technique per chracteristic (e.g. Shipto, plant, etc.).
Create new condtion records via TA /sapCND/AU11. Create a entry for TRAN and choose a access sequence. There you define a duration e.g. for a ship-to, etc.
Three options to find a transporation duration:
1. Directly from the transportation lane (TA /SAPAPO/SCC_TL1)
2. Estimated by the system if the transporation lane does not contain any duration (except if the Fix-Duration Indicator was set, note 1464309)
(The system calculates the transportation time based on the distance between the start and destination location and the average speed of the means of transport used.)
3. from the contion technique (TA /SAPCND/AU11)
(A Transportation calendar can be defined just via scheduling userexit 002 for the condition technique.)
Further details in the SAP Help Docu:

Ron,
Many thanks for your input, and I agree with your comments.
In this case, I do have a function point count which I am using for my primary
estimate. However, a prudent estimator will use multiple techniques for
comparison and reconciliation. The Class based approach, despite it's
weaknesses, appears to be a quick and simple technique to get a rough number.
As it's turned out, the function point estimate and the class based estimate
have come within 10% of each other.

Help request about customizing readings estimation

Hello,
I'm a new user of this forum and I wolud to ask you some information about customizing of readings estimation.
In particular I would:
- bypass standard SAP logics to estimate readings to use custom technique
- create custom reading type instead standard '03' value
I read previous topics in this forum and I have seen that a possible user-exit to link the new estimation logics could be EDMLELHR. Using SAP I have seen also EDMLELHA user-exit.
I think the second user-exit is better for my case because I want to create reading orders separately respect to estimation process. In fact I have had problems with EDMLELHA user-exit because after having created the reading order (EL01 transaction), in the installation I have seen in the Reading Results sheet an estimated reading. I didn't want an estimated reading, but only the reading order.
Are there way to not activate automatic estimation during EL01? Or are there other user-exit similar to EDMLELHA without this inconvenience?
Finally, how can I do to create a custom reading type after estimation?
I hope I made myself clear
Thanks a lot

Cardinality estimator 2014 is off with OR in where clause

Here is my test setup on SQL Server 2014.
-- Create big table
CREATE TABLE [dbo].[Store](
Id int IDENTITY(1,1) NOT NULL,
City int NOT NULL,
Size int NOT NULL,
Name varchar(max) NULL,
CONSTRAINT [PK_Store] PRIMARY KEY CLUSTERED ([Id] ASC)
GO
CREATE NONCLUSTERED INDEX [IX_Store] ON [dbo].[Store] (City ASC, Size ASC)
GO
-- Fill with 100k rows
INSERT Store
SELECT i % 101, i % 11, 'Store ' + CAST(i AS VARCHAR)
FROM
(SELECT TOP 100000 ROW_NUMBER() OVER (ORDER BY s1.[object_id]) AS i
FROM sys.all_objects s1, sys.all_objects s2) numbers
GO
-- Create small table
CREATE TABLE #StoreRequest (City int NOT NULL, Size int NOT NULL)
GO
INSERT #StoreRequest values (55, 1)
INSERT #StoreRequest values (66, 2)
Now I execute the following query (I force the index to show statistics estimates)
SELECT s.City
FROM #StoreRequest AS r
INNER JOIN Store AS s WITH(INDEX(IX_Store), FORCESEEK)
ON s.City = r.City AND s.Size = r.Size
WHERE s.Size <> 1 OR r.City <> 55
Here are the estimates that I get (I'm not allowed to upload pictures):
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 50000
Fixing WHERE clause to use one table not two makes the estimate perfect:
SELECT s.City
FROM #StoreRequest AS r
INNER JOIN Store AS s WITH(INDEX(IX_Store), FORCESEEK)
ON s.City = r.City AND s.Size = r.Size
WHERE s.Size <> 1 OR s.City <> 55
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 89.74
Switching to 2012 compatibility mode gives estimate of 1 in both cases:
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 1
Could anyone explain the first result? I'm a bit worried about it. The fix in this case is trivial, but this problem gave us quite some headache in more complex real life queries with multiple joins.
Thank you!

But not full statistics on a field basis, just sometimes some default stats like total row count that some plans will build. Even your StoreRequest table only has one two-field index that will have a full histogram.
But I've seen SQL Server make massively bad plans on two-field indexes.
I've seen SQL Server go wrong one-column indexes, so that is not a very relevant point.
Temp tables or not, the estimate here is clearly incorrect. SQL Server knows the density of Size and City. It knows the cardinality of the temp table. The density information gives how many rows the the join will produce. The WHERE clause will then remove
a certain number of rows. With no statistics for the temp table, it does not now how many, but it will apply some standard guess.
50000 is a completely bogus number, because the join cannot produce that many rows, and SQL Server is able to compute the join with out the WHERE clause decently. (Well, it estimates 90, when the number is 180.) No, this is obviously a case of the cardinality
estimator giving up completely.
It is worth noting that both these WHERE clauses gives reasonable estimates:
WHERE r.Size <> 11 OR r.City <> 550
WHERE s.Size <> 11 OR s.City <> 550
Whereas these two gives the spooky 50000:
WHERE s.Size <> 11 OR r.City <> 550
WHERE r.Size <> 11 OR s.City <> 550

I created an iCloud account and also had to get more space after I have done the purchase, I am unable to backup my phone! I have a stable wifi connection at home and all I see for hours and hours is "Backing Up .. Estimating time remaining"!!!!! Plz help

I created an iCloud account and also had to get more space so after I have made the purchase, I am unable to backup my phone! I have a stable wifi connection at home and all I see for hours and hours is "Backing Up .. Estimating time remaining"!!!!! Plz help I'm unable to make the backup as I need to transfer all my data on my new iPhone 5S

This may be caused by a corrupt existing backup that needs to be deleted, or by data on your device that is causing the backup to fail. To troubleshoot these, try deleting your last iCloud backup (if you have one) by turning off iCloud Backup in Settings>iCloud>Storage & Backup, then tap Manage Storage, tap your device under Backups, then tap Delete Backup. Then go back and turn iCloud Backup back on and try backing up again.
If it still won't back up, you may have an app or something in your camera roll that is causing the backup to fail. To locate which one, go to Settings>iCloud>Storage & Backup>Manage Storage, tap the name of your device under Backups, under Backup Options tap Show All Apps, then turn them all to Off (including camera roll) and try backing up again. If the backup is successful, then the camera roll and/or one of your apps is causing the backup to fail and you'll have to located by process of elimination. Turn the camera roll On and try backing up again. If it succeeds, turn some of your apps to On and try backing up again. If it succeeds again, turn some more apps to On then try again; repeat this process until it fails. Eventually you'll be able to locate the problem app and exclude it from your backup.
In the meantime you can back up your phone to your computer by connect it, opening iTunes and going to File>Devices>Back Up. Also be sure to transfer your purchases (File>Devices>Transfer Purchases). Then set up your new phone and when given the option, choose Restore from iTunes Backup and follow the prompts to restore this backup to your new phone. This will be much faster than using iCloud anyway.

Estimated costs from PM order in PS report

Hi,
In PS we have configured a reports stating. budget (wbs), planned cost (PM order), actual (Pm order). Due to the fact that the PM order is linked to the WBS code, we can see all values. Some are on WBS level, some on PM order level.
A user is requesting to have another collum stating the estimated costs that can be entered in a PM order (header level). In CJE5 you can configure the report, but can anyone of you tell me how i can configure a collum showing estimated costs on the PM order.
Thanks in advance for your help.
Kind regards,
Peter

Hi,
If you do an F1 on the estimated costs field in the order it says that this cannot be evaluated in reports and also the availability control is also not possible. So not sure whetehr you can bring this in CJE5. On the other hand the value in this fields is stored in AUFK table. So if you are using any custom reports, then you can think of pulling in this data there.

Installed Yosemite, now my MacBook Pro is running slow and the FileVault keeps saying estimating time remaining.

I installed Yosemite and since then the system has been running slow. I chose to use FileVault and it says it's encrypting but keeps saying estimating time remaining. I've tried repair permission and restarting my computer. Saw some other threads with similar problem and ran diskutil cs list which showed 80% the first time and now says failed. I also did an Entre Check and here are the results.

Please answer as many of the following questions as you can. You may already have answered some of them; in that case, there's no need to repeat the answers.
Restart the router and the broadband device, if they're separate. Any change?
Run Software Update and install all available updates for OS X or the computer's firmware. Any change?
Are you connected to Ethernet as well as Wi-Fi? If so, disconnect the Ethernet cable or adapter and test.
If possible, connect to the router with an Ethernet cable and turn off Wi-Fi. Any difference?
If you can connect to more than one network, are they all the same?
Are all network applications affected, or only some? If only some, which ones?
Is networking always the same, or is the problem intermittent?
Disconnect all other devices from the network. Any change?
If you're running a MacBook with the lid closed, open the lid. Any difference?
Start up in safe mode and test. Any difference?
Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?
If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?

HT204247 Why is my iPhone Backup WAY larger than estimated? Pics incl.

Thank you for reading!
I have an iPhone 5S 16 GB running ios 8.1.3. My iPhone is being backed up to iCloud. Currently the backup is estimated at nearly 600 MB. I am utilizing iCloud photostream. I do not have photos saved locally. The largest app under the estimate (when clicking "manage more storage" is only 12 mB.
Why is the backup SO large?!

You are welcome for reading. 600 MB backup is not large, by all means. I have no imessages, about 60 photos and my backup is over 1 Gig. You just don't realize what happens with files. If you were to create smallest file possible by using notepad on your computer and typing one letter, it would still have more then 20 kbytes. We are talking apps that require bigger files for even smallest stuff. So you can pursue that avenue - why or why or just be happy that yet you don't have to pay for storage over 5 gigs. Your poison.
