Bagaimana cara Implementasi ITIL di perusahaan?


Bagaimana cara Implementasi ITIL di perusahaan?
Ini pertanyaan yang menarik. Setelah membaca konsep ITIL, tentu anda dituntut tidak sekedar tahu saja, tapi juga bagaimana menerapkannya.
Penerapan ITIL sangat beragam tergantung dari perusahaannya.

Saya akan membagi Implementasi ITIL ini menjadi 2 case:
1.  Anda dituntut untuk menghasilkan IT service baru yang bisa memenuhi kebutuhan perusahaan.  Biasanya ini dilakukan oleh IT Service Provider. Mereka dituntut untuk menghasilkan service yang menghasilkan value bagi customer, dan tentu saja membawa benefit bagi Service Provider itu sendiri.
2. Anda sebagai bagian dari organisasi IT, di mana sudah ada IT services yang disediakan untuk customer.  Masalahnya adalah IT service ini tidak bisa dinikmati oleh user dengan optimal.
Saya akan membahas case yang ke-2 ini.
Untuk implementasi ITIL kita harus tahu apa visi perusahaan, posisi kita, dan apa yang menjadi tujuan kita.
 CSI-Initiatives

Sebenarnya ini yang menjadi inti dari Continual Service Improvement.  Model ini bisa kita gunakan untuk implementasi ITIL dalam perusahaan.

CSI Model:
1. What is the vision? Vision and business objectives
2. Where are we now? Assessments
3. Where do we want to be? Measurable targets
4. How do we get there? Process improvement or re-engineering
5. Did we get there? Measurements and targets
6. How do we keep the momentum going?

Untuk menjalankan langkah 1, kita perlu mendapatkan Formal Stakeholder Feedback.  Artinya harus ada komunikasi dengan top level management mengenai visi perusahaan dan bagaimana IT bisa bersinergi untuk mempercepat pencapaian tujuan perusahaan.  Dari sini diharapkan dukungan dari top mangement untuk ITIL Initiative.

Sebelum mengkomunikasikan ITIL Initiative anda harus benar-benar siap, sudah mempunyai ITIL Implementation Plan atau roadmap.  Anda juga harus bisa mengkomunikasikan value baik dalam istilah yang dimengerti bisnis maupun IT.  Kalau perlu anda bisa melibatkan 3rd party dalam Implementasi ITIL.
Tetapkan jalur implementasi secara bijaksana.  Mulai dengan target kecil tetapi bisa mendatangkan hasil yang cepat.  Jangan terjebak dengan keinginan untuk menerapkan semua proses di ITIL.  Dengan mengimplementasikan ITIL dalam beberapa tahapan, maka bisnis bisa melihat dan mendapatkan value IT secara lebih cepat.

Perlu diingat bahwa Implementasi ITIL sebaiknya bertahap dan merupakan proses terus-menerus/continual.
 
Langkah 2.
Kita perlu juga melakukan survei terhadap kondisi IT saat ini. Ini bisa dilakukan dengan menggunakan Maturity Model.

Langkah 3.
Pilih beberapa fungsi dan proses ITIL yang bisa mendatangkan quick wins. Mulai dengan Incident Management dan Service Desk, bisa digabungkan dengan Problem Management dan Change Management.

Langkah 4.
Membuat desain untuk masing-masing proses yang dipilih.
Incident

Langkah 5.
Membuat metric dan pengukuran.

Langkah 6.
Momentum ITIL Initiative ini perlu dijaga sehingga proses2 yang ada terus disempurnakan.  Demikian juga proses-proses baru akan bisa ditambahkan dengan baik

Ini sebabnya Draytek 2925n sangat cocok untuk online cabang Anda.

 2925-4
Dual Gigabit Ethernet WAN ports for failover and load-balancing
The Gigabit Ethernet WAN ports cater for any type of Internet access, including FTTx, xDSL and Cable fitting your local infrastructure. You can then use both WAN 1 and WAN 2 for failover, ensuring that you will always have an access to the Internet even if one of the WAN fails, or for load-balancing so the 2 WANs share Internet traffic requirements of your organization.
2 USB 2.0 ports for 3G/4G LTE mobile, FTP drive and network printers
The two USB ports can be used for the connection of 3G/4G mobile broadband dongle, FTP drive and network printers. A 3G/4G mobile broadband connected to one of the 2 USB ports can be used as a second WAN for bandwidth management. The USB WAN interface can also be the primary access if the local fixed line service hasn’t been deployed yet. You can have 2 USB 3G/4G dongles connected to the USB ports, and assign one of these (WAN 3) to be the primary access and the other (WAN 4) as the fail-over back-up. And, you have the flexibility to convert back to fixed line services when these become available.
Secured Networking
DrayTek Vigor2925 series inherited versatile firewall mechanism from previous Vigor series routers. The firewall allows setting of Call/Data Filters and DoS/DDoS prevention, whereas the CSM covers IM/P2P/Protocol filter, URL Content Filter and Web Content Filter. The object-based design used in SPI (Stateful Packet Inspection) firewall allows users to set firewall policy with ease. The object-based firewall is flexible and allows your network be safe. With Objects settings, you can pre-define objects or groups for IP, service type, keyword, file extension, etc., and mix these with the Time Scheduler or the VLAN groups as required. Altogether this gives you peace of mind whether you are guarding a complicated network or a small office. The DoS/DDoS prevention and URL/Web content filter strengthen the security outside and control inside. The enterprise-level CSM (Content Security Management) enables users to control and manage IM (Instant Messenger) and P2P (Peer-to-Peer) applications more efficiently. The CSM hence prevents inappropriate content from distracting employees and impeding productivity. Furthermore, the CSM can keep office networks threat-free and available.
By adoption of the world-leading Cyren GlobalView Web Content Filtering, you can block whole categories of web sites (e.g. sports, online shopping), subject to an annual subscription to the Cyren GlobalView WCF, which is timely updated with changed or new site categorizations. A free 30-day trial can be activated via activation wizard of Vigor2925 series routers’ web user interface. 

The "User Management" implemented on your router firmware can allow you to prevent any computer from accessing your Internet connection without a username or password. You can set scheduler or maximum usage time to your employees within office network. The user accounts can also be restricted by any other aspect of the firewall rule on a user-by-user basis.
The Vigor2925 series support DrayTek’s SmartMonitor network traffic analyzer (up to 50 nodes), which captures actual live data of activities in your managed network, such as the content of MSN entering to or out of your network. You can track specified files download/upload or view statistics on data type activities to realize what corporate related information have been released accidentally or on purpose. 

IPv6
Because the IPv4 addresses are limited and IPv6 allows for a larger address space and much more efficient routing. The Vigor2925 series support IPv6 and IPv4. The Vigor2925 series can support IPv6 broker/tunnel services to provide IPv6 access using either AICCU or TSPC via 3rd party IPv6 providers if your ISP does not support IPv6 yet.
  • can be run on any one of the WAN ports (ADSL/VDSL2, Ethernet or 3G; but the USB WAN port can run AICCU/TSPC tunnel mode only)
  • can connect to direct native IPv6 ISPs
  • can build tunnel to 3rd party IPv6 brokers using either AICCU or TSPC methods
  • Default stateful firewall for all IPv6 LAN clients/ devices
  • DHCPv6 Client
  • Static IPv6 Client
  • DHCPv6 & RADVD (Router Advertisement Server) for client configuration
  • QoS for IPv6 with DiffServ
  • IP Filtering Rules
  • Router Management over IPv6 (Telnet/HTTP) with IPv6 access list
  • Concurrent operation with IPv4 (“Dual-Stack”)
  • Other router features are only available on IPv4

VLAN for secure and efficient workgroup management
Not only with 5 x Gigabit LAN ports for the needs of unified communication applications, such as CRM server, FTP server, Mail server, the Vigor2925 Series has the comprehensive VLAN function for management. The VLAN functions allow 5 subnets to be allocated for multiple workgroups. When combined with the NAT and firewall functions, you can design corporate network groups in terms of traffic, security level, priority settings, etc.
Applications such as VoIP, IPTV and Wireless SSID can also be integrated into VLAN tags and firewall objects, giving you the maximum flexibility in designing workgroups for your organization.
Comprehensive VPN
For remote teleworkers and inter-office links, Vigor2925 series provide up to 50 simultaneous VPN tunnels (such as IPSec/PPTP/L2TP protocols) for secure data exchange and communication. With a dedicated VPN co-processor, the hardware encryption of AES/DES/3DES and hardware key hash of SHA-1/MD5 are seamlessly handled, thus maintaining maximum router performance. Teleworkers can be authenticated directly with your LDAP server if preferred. The Vigor2925 series are equipped with two Gigabit Ethernet ports and USB WAN ports for WAN load-balancing and backup. The VPN trunking (VPN load-balancing and VPN backup) are hence implemented on Vigor2925 series. With VPN trunking, you can create multiple WAN connections to a remote site in order to increase bandwidth. The VPN trunking also can allow you to have failover (backup) of VPN route through a secondary WAN connection.
With SSL VPN, Vigor2925 series let teleworkers have convenient and simple remote access to central site VPN. The teleworkers do not need to install any VPN software manually. From regular web browser, you can establish VPN connection back to your main office even in a guest network or web cafe. The SSL technology is same as the encryption that you use for secure web sites such as your online bank. The SSL VPNs can be operated in either full tunnel mode or Proxy mode.
For client-to-site, remote dial-in users can use up-to 25 SSL VPN tunnels to avoid the local network infrastructure limitation, , there are 64 profiles on WUI, but it only allows 25 concurrent tunnels.
Multi-subnet
With the 5-port Gigabit switch on the LAN side provides extremely high speed connectivity for the highest speed local data transfer of any server or local PCs. The tagged VLANs (802.1q) can mark data with a VLAN identifier. This identifier can be carried through an onward Ethernet switch to specific ports. The specific VLAN clients can also pick up this identifier as it is just passed to the LAN. You can set the priorities for LAN-side QoS. You can assign each of VLANs to each of the different IP subnets that the router may also be operating, to provide even more isolation. The said functionality is tag-based Multi-subnet.
Each of the wireless SSIDs can also be grouped within one of the VLANs.
With multi-subnet, the traffic can be sent through non-NAT mode with higher performance.   If you deploy Vigor2925 series with MPLS network with your main office, the multi-subnet settings will let your data transactions be carried out without NAT.
Centralized Management 
With F/W 3.7.4, the embedded Central VPN Management (CVM) will let network administrator register up to 16 remote routers but run concurrent remote management over 8 remote routers.
AP Management 
APM provides the 3-step installation, plug-plug-press, and then wireless clients are able to enjoy surfing internet. Moreover, through the unified user interface of Draytek routers, the status of APs is clear at the first sight.
If your network requires several VigorAP900 or VigorAP 810 units, to centrally manage and monitor them individually as a group will be expected. DrayTek central wireless management (AP Management) lets control, efficiency, monitoring and security of your company-wide wireless access easier be managed. Inside the web user interface, we call “central wireless management” as Central AP Management which supports mobility, client monitoring/reporting and load-balancing to multiple APs.  For central wireless management, you will need a Vigor2860 or Vigor2925 series router; there is no per-node licensing or subscription required.  For multiple wireless clients, to apply the AP Load Balancing to the multiple APs will manage wireless traffic with smooth flow and enhanced efficiency.
Supports Smart Monitor traffic report software
Vigor2925 series routers support Smart Monitor, DrayTek's proprietary network traffic reporting software, for up to 50 users. This software monitors all incoming and outgoing network traffic, categorizes these into various activity and data types and provides statistics in various report types, so network administrators can monitor network activities for planning and/or fault locating purposes.
Concurrent dual-band 802.11n WLAN (2.4G/5G)
Vigor2925n plus and Vigor2925Vn plus have a built-in IEEE 802.11n WLAN Access Point with concurrent dual-band (2.4G/5G). They can allow the essential applications to use the less interference band (e.g. 5G). The Wi-Fi access is also protected by security and encryption protocols, including WEP/WPA/WPA2, MAC Address Control, Multiple SSID, Wireless LAN Isolation, Wireless VLAN* and 802.1x Authentication.
The Wireless Rate Control function allows connection rates for each network device to be individually managed as required. The WMM (Wi-Fi Multi-Media)* function allows setting of priority levels for various applications: voice, video, data, etc., so time-critical applications can be assigned higher priority levels. Furthermore, WDS (Wireless Distribution System) function allows you to extend the wireless coverage distance easily.

Flexible Network Management
Like all DrayTek routers, Vigor2925 Series routers support comprehensive network management functions. For example, you can set username/password and directory/file access privilege for individual users as required. There are also routing/network tables, system log, debugging utilities, etc., making network administrators' jobs easy.
Other management features include SNMP, TR-069 and TR-104. TR-069 can be utilized with DrayTek's VigorACS SI management software to remotely monitor and manage the Vigor2925 Series.
